Prior to my conversion several years ago, I had absolutely no assurance of salvation, because I was trusting in works for salvation, being raised in the Roman Catholic church, which taught that assurance of salvation was the sin of presumption.
It was not until I placed my faith (belief, trust, reliance) in CHRIST ALONE for salvation that I knew without a doubt that I had become born again and was saved. Praise God!
1 John 5:11 - And this is the testimony: that God has given us eternal life, and
this life is in His Son. 12
He who has the Son has life; he who does not have the Son of God does not have life. 13 These things I have written to you who
believe in the name of the Son of God, that you may
know that you have eternal life, and that you may continue to believe in the name of the Son of God.
Romans 8:16 -
The Spirit Himself bears witness with our spirit that we are children of God.
