“If God loved us because we loved Him, He would love us only so long as we loved Him and on that condition, and then our salvation would depend on the constancy of our treacherous hearts, but as God loved us as sinners, as Christ died for us as ungodly, our salvation depends, not on our loveliness, but on the constancy of God’s love.”
— Charles Hodge, Commentary on Romans (on Romans 5:8)
That is the whole chain in one bolt. Peace with God isn’t something you maintain — it’s a verdict that was handed down and can’t be appealed. God didn’t reconcile you because you were worth reconciling. He reconciled you while you were His enemy. And if He did that when you were running from Him, what does He do now that He’s brought you home?
Verse 10 puts it like a hammer: “For if, when we were enemies, we were reconciled to God by the death of His Son, much more, being reconciled, we shall be saved by His life.”
If a dead Savior can save you, a living Savior will keep you.
Your salvation never depended on your grip on Him. It depended on His grip on you. And He doesn’t let go.
