Will the holy men of God such as the prophets and the apostles who were killed and some were even beheaded, be thrown into the lake of fire because they "earned their salvation" (as implied) by OBEYING AND TEACHING OBEDIENCE TO GOD?
The FREE GIFT of God is His only begotten Son Jesus Christ.
(Romans 6:23, revelations 22:17)
“For God so loved the world that HE GAVE HIS ONLY BEGOTTEN SON, that whoever believes in him shall not perish but have ETERNAL LIFE. For God did not send his Son into the world to condemn the world, but to save the world through him. Whoever believes in him is not condemned, but whoever does not believe stands condemned already because he has not believed in the name of God’s one and only Son. This is the verdict: Light has come into the world, but men loved darkness instead of light because their deeds were evil. Everyone who does evil hates the light, and will not come into the light for fear that his deeds will be exposed. But whoever lives by the truth comes into the light, so that it may be seen plainly that what he has done has been done through God.” John 3:16-21
...Now THIS IS ETERNAL LIFE: THAT THEY MAY KNOW YOU, the only true God, and Jesus Christ, whom you have sent. John 17:3
Then John said;
...WE KNOW THAT WE HAVE COME TO KNOW HIM IF WE OBEY HIS COMMANDS. The man who says, “I know him,” but does not do what he commands is a LIAR, and THE TRUTH IS NOT IN HIM. But if anyone obeys his word, God’s love is truly made complete in him. This is how we know WE ARE IN HIM: Whoever CLAIMS to live in him MUST WALK as Jesus did. 1 john 2:3-6
WE CAN BE IN JESUS IF WE OBEY THE COMMANDMENTS. HE IS THE LIFE THAT WE MUST ENTER IN. (john 14:6)... ETERNAL LIFE IN CHRIST JESUS. (Romans 6:23)
...If you want TO ENTER LIFE, obey the commandments.” matthew 19:17
...Although he was a son, HE LEARNED OBEDIENCE FROM WHAT HE SUFFERED hebrews 5:8
...To this you were called, because Christ SUFFERED for you, LEAVING YOU AN EXAMPLE, that YOU SHOULD FOLLOW IN HIS STEPS. 1 Peter 2:21
...For it has been granted to you on behalf of Christ NOT ONLY TO BELIEVE IN HIM, but also TO SUFFER FOR HIM, Philippians 1:29
Those who truly believes in the Son of God loves the light and Jesus is the LIGHT of the world.
Whoever loves Jesus stays in the light and OBEYS His commands. Whoever does not OBEY His commands hates the LIGHT. Whoever hates the LIGHT, hates God. Whoever hates God are ENEMIES of God.
...As far as the gospel is concerned, they are ENEMIES on your account; but as far as election is concerned, they are loved on account of the patriarchs, for God’s gifts and his call are IRREVOCABLE. Romans 11:28-29
...THEY STUMBLE BECAUSE THEY DISOBEY THE MESSAGE—which is also what they were destined for. 1 Peter 2:8
Paul was talking here about GOD'S calling and gifts to Israel.
...the people of Israel. Theirs is the adoption as sons; theirs the divine glory, the covenants, the receiving of the law, the temple worship and the promises. Theirs are the patriarchs, and from them is traced the human ancestry of Christ, who is God over all, forever praised! Amen. Romans 9:4-5
...This is IRREVOCABLE.
But what did he say to the Gentiles?
...I am talking to you Gentiles. In as much as I am the apostle to the Gentiles, I make much of my ministry in the hope that I may somehow arouse my own people to envy and save some of them. For if their rejection is the reconciliation of the world, what will their acceptance be but life from the dead? If the part of the dough offered as firstfruits is holy, then the whole batch is holy; if the root is holy, so are the branches. If some of the branches have been broken off, and you, though a wild olive shoot, have been grafted in among the others and now share in the nourishing sap from the olive root, DO NOT BOAST OVER THOSE BRANCHES. If you do, consider this: You do not support the root, but the root supports you. You will say then, “Branches were broken off so that I could be grafted in.” Granted. But they were broken off because of unbelief, and you stand by faith. DO NOT BE ARROGANT, BUT BE AFRAID. For if God did not spare the natural branches, HE WILL NOT SPARE YOU EITHER. Consider therefore the kindness and sternness of God: sternness to those who fell, but kindness to you, PROVIDED that you continue in his kindness. Otherwise, YOU ALSO WILL BE CUT OFF. And if they do not persist in unbelief, they will be grafted in, for God is able to graft them in again. After all, if you were cut out of an olive tree that is wild by nature, and contrary to nature were grafted into a cultivated olive tree, how much more readily will these, the natural branches, be grafted into their own olive tree! Romans 11:13-24
...But our citizenship is in heaven. And WE EAGERLY AWAIT A SAVIOR from there, the Lord Jesus Christ,
Philippians 3:20
...And do this, understanding the present time. The hour has come for you to WAKE UP from your slumber, because OUR SALVATION IS NEARER NOW THAN WHEN WE FIRST BELIEVED . Romans 13:11
