Have you ever doubted your salvation? Perhaps your bad habits have caused you to wonder if God will change His mind about you. Or maybe you’ve made one life-changing mistake, and it seems there could be no way to get right with God. The good news is that eternal life is a gift we receive through faith in Jesus Christ. Our assurance of salvation does not depend on who we are or what we’ve done.
How can we remain confident in this knowledge? Memorizing Scripture is one of the best ways to preserve our assurance of salvation. When we know God’s Word by heart and can call passages to mind, the Holy Spirit uses these truths to calm our fears and restore our inner peace.
In his book 100 Bible Verses Everyone Should Know by Heart, Robert Morgan shares insights and a verse that can provide us great assurance of salvation when we feel tempted to doubt:
And this is the testimony: God has given us eternal life, and this life is in His Son.
1 John 5:11
As a college sophomore, I was mentored by an upperclassman who gave me these two verses, 1 John 5:11-12, to memorize. He called them two of the best verses in the Bible about assurance of salvation. As long as I knew these verses, he said, I’d never doubt being saved. I’ve come back to them many times, and I’m thankful for what’s not in them. There is no maybe, if, might, or hope so…
This is the testimony. This is what God himself has declared as truth. This is the record. These are the facts.
He has . . . It’s already done. This has been irrevocably accomplished.
He has given us . . . It’s not just a generic promise that He has given eternal life. It includes that personal pronoun us. And us includes you and me.
He has given us eternal life. While the whole Bible teaches that God is eternal and He bestows everlasting life on His children, it’s John who is the apostle of eternal life. He used the phrase twenty-three times in His writing.
And this life is in His Son. Jesus not only gives us life; He is the Source and Creator of life. And yet—paradox of the ages—He died to conquer death, and because he lives, we live also.

“Our hope is not hung upon such an untwisted thread as, ‘I imagine so,’ or ‘it is likely,’ but the cable, the strong tow of our fastened anchor, is the oath and promise of Him who is eternal verity. Our salvation is fastened with God’s own hand, and with Christ’s own strength, to the strong stake of God’s unchangeable nature.” –Samuel Rutherford
