Someone asked in Yahoo Answers: “Is it possible to fall from grace? Like if you submit yourself to God, is it possible to lose your salvation? For example.. if you become a Christian,like a full fledged Chrisitan, then suddenly become an atheist and claim God isn’t real…would you be denied entry to heaven when you die? I’m 15 so go easy on me, haha. And atheists, please dont pester me. Nothing is gonna change my mind about my belief.”
As far as God is concerned, Jesus is the Saviour of all men. God has reconciled everyone to Himself through Christ.
Falling from grace is not the same as “losing salvation”. Actually, no one can lose salvation because salvation is a Person. Jesus (Yeshua in Hebrew) means Salvation.
Galatians 5 says those who seeks to be made righteous by the law (that is, by their self-efforts or performance), they have fallen from grace. The verse doesn’t say those who sin or “reject Christ” (I’m using christian lingo here) fall from grace.
Salvation is not about being saved from a place called hell in future. Salvation is for the here and now. We are saved from a wrong mindset about God and ourselves when we believe the good news that God is one with us, and Christ in us is the hope of glory. Jesus is God and He came to show us what God is like. God is love, and only love, and love keeps no records of wrongs.
As long as we rest in knowing we are already blessed and innocent, as we are made in His image, we can expect good things to happen and grace continues to flow in our lives effortlessly, without us trying to earn favour by our efforts.
