1 Timothy 1:15-16, The saying is trustworthy and deserving of full acceptance, that Christ Jesus came into the world to save sinners, of whom I am the foremost. But I received mercy for this reason, that in me, as the foremost, Jesus Christ might display His perfect patience as an example to those who were to believe in Him for eternal life.
Do not be like the Calvinist and think, “Am I truly among God’s elect?” For “limited atonement” is the trickery of the Devil to get the elect to doubt and fall from God’s grace. (For under the false doctrine of limited atonement, no one can be certain of their salvation, but are left to wonder for the rest of their lives, without any assurance, if God has chosen them.) If you ever wonder if you truly are elect, look at the Word! What does it say? “For God so loved the world [that includes you], that He gave His only Son, that whoever believes in Him should not perish but have eternal life” (John 3:16).
There you have it. Do you believe Christ died and rose from the dead for you? If your answer is yes, then the answer to your question, “Am I truly among God’s elect?” can only be yes. To wonder and exclude yourself from the elect when you do believe is to call God a liar.
This promise is for every sinner—yes, even murderers, pedophiles, child molesters, terrorists, abortionists, or whatever other sins you deem unforgivable; for Paul is our example of God’s grace in Christ. Can God forgive a murderer, child molester, pedophile, abortionist, and so on? Yes! For Paul was a murderer, David was a murderer, the woman was an adulterer (John 8:1-11), and so on. Jesus forgave all these and more.
Jesus forgives even your great sin, whatever it is. Again, to say God cannot or will not forgive such sins is to call God a liar. A God who does not forgive such sins is not the God of Christianity. If you do not believe God can forgive such grave sins, then you and I believe in different Gods, and my God is filled with much more grace than you can imagine.
