Where shall I start? First with your assumption that one will continue practicing sin after salvation. The first thing to understand is that people who love sin more than righteousness are not seeking salvation. They are trying to avoid the results of sin. So, why would they not go on Sydney that’s what they desire but they aren’t saved and they really don’t want to be.
Is sinning something you want to continue doing? If you don’t why not? If it’s because you fear punishment that’s not acceptable to God. God wants a father son relationship with you not an “obedience” out of fear relationship.
We see God in the first place because he draws us to him and what are the chords he uses to draw us to him? He draws us with chords of love not cords of fear.
Hosea 11:4 NIV
I led them with cords of human kindness, with ties of love. To them I was like one who lifts a little child to the cheek, and I bent down to feed them.
Heb 10.14 For by his one sacrifice he is perfected us forever while we are still being made holy.
For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast.
He saved us, not because of works done by us in righteousness, but according to his own mercy, by the washing of regeneration and renewal of the Holy Spirit,
And there is salvation in no one else, for there is no other name under heaven given among men by which we must be saved.”
Because, if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved.
For by grace you have been saved through faith. And this is not your own doing; it is the gift of God,
“For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life.
Because, if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved. For with the heart one believes and is justified, and with the mouth one confesses and is saved
Are you worried about overcoming is Revalation commands us to? Then worry no more because Christ saidTake heart for I have overcome the world. Therefore, the only thing we have to overcome is our lack of faith in believing what he has done for us. That is what Jesus meant by “abiding in him.”
