"And he who was seated on the throne said, “Behold, I am making all things new.” Also he said, “Write this down, for these words are trustworthy and true.” And he said to me, “It is done! I am the Alpha and the Omega, the beginning and the end. To the thirsty I will give from the spring of the water of life without payment. The one who conquers will have this heritage, and I will be his God and he will be my son. But as for the cowardly, the faithless, the detestable, as for murderers, the sexually immoral, sorcerers, idolaters, and all liars, their portion will be in the lake that burns with fire and sulfur, which is the second death.”" Revelation 21:5-8
The bottom line of salvation is have you have your sins forgiven? Christ is the forgiveness. There is no other forgiveness from God for our sins other than coming to Christ, and trusting in Him, and with a heart of godly sorrow ask Him to have mercy on our souls. This is salavtion. It's 100% pure grace. It's God's favor and mercy that we must receive. Once we do, all our sins are blotted out, and we are righteous in His sight, because we are one with Christ through the baptism of the Holy Spirit, which Jesus administers to all who cry out to Him.
What an awesome and gracious God and Savior we have!
But for those who reject Christ, or are simply indifferent, these will have to answer for their sins, and lawlessness, veven those who seem to be believers in the Lord.
For the Lord Jesus says:
“Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but the one who does the will of my Father who is in heaven. On that day many will say to me, ‘Lord, Lord, did we not prophesy in your name, and cast out demons in your name, and do many mighty works in your name?’ And then will I declare to them, ‘I never knew you; depart from me, you workers of lawlessness.’"
There's much more to this, and it's all there in the Bible, the Holy Scriptures, God's Word. Please read it for yourselves, and pray. God is a longsuffereing God, but He does have a wrath, and He will punish sinners, and they will not inherit eternal life, but shall perish.
John 3:16:"“For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life. For God did not send his Son into the world to condemn the world, but in order that the world might be saved through him." -Jesus Christ
