It’s impossible to explain and beyond our comprehension, but the hope of eternal life offered by the Gospel of Jesus Christ is something that God promised before the world began:
Paul, a servant of God and an apostle of Jesus Christ, for the sake of the faith of God’s elect and their knowledge of the truth, which accords with godliness, in hope of eternal life, which God, who never lies, promised before the ages began…Titus 1:1–2, ESV
Think of that a moment. Before the first “Let there be” was uttered, the plan of redemption was already in place. Before man existed, his fall was anticipated, and its remedy already worked out. In addition, Paul declares in 2 Timothy 1:9 that the grace bestowed upon the repentant sinner was “given us in Christ Jesus before the world began.”
So the planting of the tree of the knowledge of good and evil and God’s command to Adam not to eat of it was not, from God’s perspective, a test to see whether man would choose to obey God or choose to follow his own desires.
God knew already what was coming.
He knew of Satan’s serpentine tactics, of Eve’s longing look at the fruit, of her distorted thinking. He saw her bite the fruit before the fruit was formed. And He knew what Adam would do, that he would opt for unity with his wife rather than fellowship with his Creator. God knew Adam would eat the fruit with her; He knew the death penalty that would fall upon humanity.
Absolutely nothing took God by surprise.
Hence the promise.
And the promise is sure because it’s rooted in the character of God. He “cannot lie,” Paul affirms. Lying, falsehood, untruth, misspeaking—whatever you want to call it—is beyond the capability of the Creator. When He declared, “Adam’s going to sin, but I’ve got a glorious plan of redemption established that will ensure eternal life for every one of his descendants who believe me, upon whom my grace will be bestowed through my Son, Jesus,” He meant every word.
So, my friend, if you have responded to the message of redemption by believing it, repenting of your sin, and wholly trusting in the person and work of the Lord Jesus Christ, you have an eternal promise from God your Creator that eternal life is yours.
On that you can rest assured!
