“I don’t know the exact time and date I was saved. I’ve been told that I should know this if I’m truly saved. Is this true?”
Knowing your spiritual birthday is not required at all. Whether you know in your heart that you’ve placed your faith in the gospel of grace that Christ died for your sins personally, was buried, and rose again is what is required for your salvation (Eph. 2:8,9; 1 Cor. 15:3,4).
The idea that you have to know an exact time you were saved doesn’t come from the Bible. It comes from man. Our confidence for our salvation shouldn’t be in a date anyway. Our confidence is in Christ, His Cross, and the Word of God. “The Lord knoweth them that are His” (2 Tim. 2:19), and if you’ve placed your faith in Christ that He died for you and rose again, you are His. Praise the Lord! source
