If youβre not familiar with what is called βthe sinnerβs prayer,β it is a prayer that basically repeats the facts of the simple message of salvation. There are many variations of the prayer, but it usually sounds something like, βGod, I know Iβm a sinner and deserve to die for my sins; but I know that Christ died for my sins, and rose again. I believe this, and I ask You to save me.β
Now, that certainly sounds innocent enough, doesnβt it? I mean, itβs just praying the specifics of the gospel out loud (1 Cor. 15:3,4). What could be wrong with that?
The thing that makes praying the sinnerβs prayer not a good idea is that God never asks us to pray the gospel, He only asks us to believe the gospel. So asking someone to pray the gospel is adding to Godβs simple requirement for salvation. And, if you think it through, it is adding a work to the receiving of something God says is a gift (Rom. 6:23).
Perhaps you are thinking, βPrayer is a work?β Well, in writing to the Colossians, the Apostle Paul spoke well of a man named Epaphras, whom he described to them as βalways laboring fervently for you in prayersβ (Col. 4:12). If you can labor in prayer, then prayer must be a work. It may not be a very big work, but salvation today is by grace through faith alone (Eph. 2:8,9; Titus 3:5), and the moment you add even the slightest work to grace, it ceases to be grace (Rom. 11:6).
Another problem with asking a sinner to pray the sinnerβs prayer is that years later he/she may wonder if they prayed it right, if they said the right words in the right way. And since the sinnerβs prayer is not in the Bible, they cannot check to see if they prayed it right, which may cause them to question if they are truly saved.
Now if you prayed the sinnerβs prayer when you were saved, you neednβt wonder if praying this prayer somehow negated the gospel you believed to be saved. Many Christian have prayed this prayer as well, but praying the gospel isnβt what saved us. Believing the gospel is what gave us eternal life. The moment you believed the gospel, you trusted Christ with your eternal destiny, a process Paul describes in Ephesians 1:13 with no mention of praying the sinnerβs prayer. Speaking of Christ, he says,
βIn whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that Holy Spirit of promise.β
Paul says that after you believed the facts of the gospel, you were saved and sealed with the Spirit. God did not wait until you asked to saved by repeating the facts of the gospel in prayer. No, you were sealed for time and eternity from the very moment of belief. source
