What if you have faith, yet you hate God with all your heart and laugh at his commandments every day of your life?
Then I guess you don’t really have faith, do you?
Once one has had a changed heard through realizing God’s Grace in giving Christ a sacrifice for one’s personal sin (for WHICH I VERY MUCH DESERVE HELL AND DEATH) one can’t go about acting like you just described once the Holy Spirit has caused a person to be “born of the spirit” (He wouldn’t be very effective if He couldn’t do this in a person’s life). I am not the only one I submit the life of the apostle Paul as but one example, and others as well including old testament believers like Abraham and King David (who were very much sinners, but through belief in their future Messiah-Jesus) they too were saved!
-Happy Easter, btw Y’all ;)!
