Walking in the light is directly related to following Jesus, who said, "I am the light of the world. He who follows me shall not walk in darkness, but have the light of life" (John 8:12). Walking in darkness is the exact opposite of walking in the light. To walk is to con*duct one*self in a cer*tain man*ner; to live; to walk. Walk*ing in the light is syn*ony*mous for the Chris*t*ian way of life. Those who walk in the light practice righteousness and not sin and also love their brother and those who walk in darkness practice sin and not righteousness and hate their brother (1 John 2:9-11; 3:9-10).
Did they walk in all the commandments and ordinances of the Lord in order to become righteous or because they were righteous by faith? Which is cause and which is effect? Do you believe blameless means they lived sinless, without fault or defect, flawless perfect lives 100% of the time?
What does Genesis 15:6 say? Abraham walked before God, became perfect and it was merited to him for righteousness? NO. Abraham BELIEVED the Lord and it was credited to him for righteousness. Abraham walked before God because he was a righteous man, not in order to become a righteous man.
So the only thing you see when you read these verses is salvation by works/legalism? I NEVER said that all the walking cited above is legalism. It's not legalism when it's done for the right reason with the right motivation. Salvation by works is NOT the right reason or the right motivation. I am not arguing that those who do NOT keep Christ's commands and walk in darkness not walking according to Christ's word will be saved anyway. That is descriptive of lost unbelievers, not born again believers. Keeping Christ's commands/walking in the light according to Christ's word is descriptive of those who are saved. You continue to put the cart before the horse.
Without faith in Christ we don't obey by getting water baptized. We just get wet. Works apart from faith is not obedience. You have faith/trust in water baptism/works to save you (Ephesians 2:9; Titus 3:5; 2 Timothy 1:9) and your faith/trust is not exclusively in Christ's finished work of redemption to save you (1 Corinthians 15:1-4; Romans 1:16). We are saved by grace through faith and not by water and works.
In Colossians 2:12, the context shows that baptism is presented as the New Testament counterpart of circumcision in the Old Testament. They are presented in a careful parallel to each other. The one who is "in Christ" is circumcised with a circumcision made "without hands." The parallel usage of circumcision and baptism demands that we understand the "baptism" to be made "without hands" also. Romans 2:28-29 shows clearly that it is not physical circumcision "made with hands" but spiritual circumcision which makes one truly a Jew and one of Abraham's children. Since baptism is the New Testament counterpart to circumcision in the Old Testament, we may therefore understand Romans 2:28-29 to have the same meaning in relation to baptism that it has in relation to circumcision: For he is not a Jew who is one outwardly, nor is that circumcision which is outward in the flesh; but he is a Jew who is one inwardly, and circumcision is that of the heart, in the Spirit, and not in the letter, whose praise is not from men but from God. Physical circumcision was not necessary for salvation in the Old Testament, for Abraham was saved when he BELIEVED before he was circumcised (Genesis 15:6). The same applies to physical water baptism in the New Testament (Acts 10:43-48). Raised with Him through faith in the working of God. The working of God is Spirit baptism and raising Him from the dead, not water baptism (1 Corinthians 12:13; Romans 4:24). Notice, "by ONE SPIRIT we were all baptized into ONE BODY..." (1 Corinthians 12:13). Also notice, "It shall be imputed to us who BELIEVE IN HIM who raised up Jesus our Lord from the dead.." (Romans 4:24). That is God's work. The object of our faith in receiving salvation is Christ's finished work of redemption (Romans 3:24), not water baptism.
In regards to refusing to be water baptized. In Luke 7:29, we read - When all the people and the tax collectors heard this, they justified God/acknowledged God's justice, (signified by) having been baptized with the baptism of John. 30 But the Pharisees and the lawyers rejected God's purpose for themselves, (signified by) not having been baptized by John. I don't believe that baptism magically made them become disciples of John but their decision to become disciples of John was signified in baptism. Just like becoming a disciple of Jesus is signified, yet not procured in the waters of baptism. Becoming a disciple of Jesus is a heart decision that is made prior to becoming water baptized. Refusing to become a disciple of Jesus is signified in refusing to be baptized.
