Walking after Jesus following salvation is sanctification, but it isn't justification. Justification occurs regardless of our good works, as a free gift, through the washing and regeneration of the Holy Spirit. Justification isn't sanctification..different things.
So your insight is the dogmas of Martin Luter is the "truth." My challenge is this: Jesus said "He that endures to the end will be saved, and in support of 1518 Luter - who later changed his name to Luther - you buy lock and barrel his justification/sanctification dogma.
Far be it from me to disagree with sacred Luther.....but lets look at Matthew 25 and explain to me how one "is Justified" without ever being Sanctified. Let's start with Paul who tells us that you may have "faith" to move mountain but do not have love you are just making noise to God and in Galatians 5 describes the fruits of the Spirit. Although Luther was all about conversion of life, his modern day followers, wanting instant salvation, put instant salvation waaay ahead of what they claim is "justification"... Fortunately, Luther did not die on the cross for our sins.
So, in your ancient model, where is someone who is "justified" who has no love, exhibits no "fruits of the Spirit" and could not be picked out of a crowd of heathens by their live style and priorities and commitments? Are you and Luther suggestion that "Justification" without "Sanctification" is exactly the same as "once saved always saved" without any Justification? If not, then isn't Justification the real source salvation validation? Everyone can claim salvation without justification because Luther et. al. said if you are justified then you will experience life long devince sanctification and if you don't, you were never sanctified in the first place. Circular logic where you have zero assurance of salvation until you live out a set-apart holy life in justification. By inference, if you claim salvation without justification you are deluding yourself.
Matthew 7: 21 "Not everyone who says to me, 'Lord, Lord,' will enter the kingdom of heaven, but only the one who does the will of my Father who is in heaven. (Justification before sanctification) 22 Many will say to me on that day, 'Lord, Lord, did we not prophesy in your name and in your name drive out demons and in your name perform many miracles?'23 Then I will tell them plainly, 'I never knew you. Away from me, you evildoers!'" Obedience in life trumps any claim of salvation you might make. Essentially you are judged by what you do (justification) and not only by what you claim to "believe." (sanctification) Even Luther was adamant that truely converted Christ followers will live lives bearing much fruit, if not, they deceived themselves.
So, what are the components of "justification?"
Love God and love your neighbor as yourself - and in the story of the Good Samaritan - your neighbor is anyone you can physically and financially help.
“And he saith unto them, Follow me, and I will make you fishers of men” (Matthew 4:19).
Rejoice
“Blessed are you when people insult you, persecute you and falsely say all kinds of evil against you because of me. 12Rejoice and be glad, because great is your reward in heaven, for in the same way they persecuted the prophets who were before you. (Matthew 5:11–12).
Let Your Light Shine
“Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven” (Matthew 5:16).
Be Reconciled
“Therefore, if you are offering your gift at the altar and there remember that your brother or sister has something against you, leave your gift there in front of the altar. First go and be reconciled to them; then come and offer your gift. (Matthew 5:23–25).
Do Not Lust
“You have heard that it was said, ‘You shall not commit adultery.’ But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart.
Be a Giver
“You have heard that it was said, ‘Eye for eye, and tooth for tooth.’ But I tell you, do not resist an evil person. If anyone slaps you on the right cheek, turn to them the other cheek also. And if anyone wants to sue you and take your shirt, hand over your coat as well. If anyone forces you to go one mile, go with them two miles. Give to the one who asks you, and do not turn away from the one who wants to borrow from you. (Matthew 5:38–42).
Love Your Enemies
“You have heard that it was said, ‘Love your neighbor i and hate your enemy.’ But I tell you, love your enemies and pray for those who persecute you, that you may be children of your Father in heaven. He causes his sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous. If you love those who love you, what reward will you get? Are not even the tax collectors doing that? And if you greet only your own people, what are you doing more than others? Do not even pagans do that? Be perfect, therefore, as your heavenly Father is perfect.” (Matthew 5:44–46).
Give to the Needy
“Be careful not to practice your righteousness in front of others to be seen by them. If you do, you will have no reward from your Father in heaven. So, when you give to the needy, do not announce it with trumpets, as the hypocrites do in the synagogues and on the streets, to be honored by others. Truly I tell you, they have received their reward in full. But when you give to the needy, do not let your left hand know what your right hand is doing, so that your giving may be in secret. Then your Father, who sees what is done in secret, will reward you. Matthew 6:1–18).
Don’t Judge Others
“Do not judge, or you too will be judged. For in the same way you judge others, you will be judged, and with the measure you use, it will be measured to you. “Why do you look at the speck of sawdust in your brother’s eye and pay no attention to the plank in your own eye? How can you say to your brother, ‘Let me take the speck out of your eye,’ when all the time there is a plank in your own eye? You hypocrite, first take the plank out of your own eye, and then you will see clearly to remove the speck from your brother’s eye. (Matthew 7:1–3).
Ask, Seek, Knock
“Ask and it will be given to you; seek and you will find; knock and the door will be opened to you. For everyone who asks receives; the one who seeks finds; and to the one who knocks, the door will be opened. (Matthew 7:7–8).
Do Unto Others
“Therefore, all things whatsoever ye would that men should do to you, do ye even so to them: for this is the law and the prophets” (Matthew 7:12).
Take My Yoke
“Come to me, all you who are weary and burdened, and I will give you rest. Take my yoke upon you and learn from me, for I am gentle and humble in heart, and you will find rest for your souls. For my yoke is easy and my burden is light.” (Matthew 11:28–30).
Deny Yourself
“If any man will come after me, let him deny himself, and take up his cross daily, and follow me. For whoever will save his life shall lose it: but whoever will lose his life for my sake, the same shall save it. For what good is it for a man, if he gain the whole world, and lose himself, or be cast away?” (Luke 9:23–25).
Go to Offenders
“If your brother or sister sins, go and point out their fault, just between the two of you. If they listen to you, you have won them over. But if they will not listen, take one or two others along, so that ‘every matter may be established by the testimony of two or three witnesses.’ If they still refuse to listen, tell it to the church; and if they refuse to listen even to the church, treat them as you would a pagan or a tax collector. (Matthew 18:15–17).
Forgive Offenders
“Then came Peter to him, and said, Lord, how oft shall my brother sin against me, and I forgive him? till seven times? Jesus saith unto him, I say not unto thee, Until seven times: but, Until seventy times seven” (Matthew 18:21–22).
Humility
“. . . Whosoever will be great among you, let him be your minister; and whosoever will be chief among you, let him be your servant: even as the Son of man came not to be ministered unto, but to minister, and to give his life a ransom for many” (Matthew 20:26–28).
Bring In the Poor
Then Jesus said to his host, “When you give a luncheon or dinner, do not invite your friends, your brothers or sisters, your relatives, or your rich neighbors; if you do, they may invite you back and so you will be repaid. But when you give a banquet, invite the poor, the crippled, the lame, the blind, and you will be blessed. Although they cannot repay you, you will be repaid at the resurrection of the righteous.” (Luke 14:12–14).
Love Your Neighbor
“And the second [commandment] is like it, You shall love your neighbor as yourself. On these two commandments hang all the law and the prophets” (Matthew 22:39–40).
Be Born Again
“Very truly I tell you, no one can see the kingdom of God unless they are born again. (John 3:5–7).
Keep My Commandments
“If ye love me, keep my commandments” (John 14:15)
Baptize My Disciples
“Go therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost” (Matthew 28:19).
Make Disciples
“Go therefore, and teach all nations . . . teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you always, even unto the end of the world. Amen” (Matthew 28:19–20).
