Question - Please Help

I’ve really been trying to work this out and it’s really bothering me, please help

I’m a sinner, I will be a sinner until I die. To sin is to turn my back on God

While I accept this, I don’t think it negates personal responsibility for my actions. Each action is a choice. I am capable of making the choice not to put money in my pocket and steal. I am capable of not - almost any sin except random thoughts that pop into my head. Tempted or not, I am capable of choosing my actions and know right from wrong. I don’t accidentally get drunk or accidentally cheat someone

So how do I reconcile telling Jesus I’m going to follow Him (Prayer of Salvation) KNOWING I WILL sin again

Each choice to sin is turning my back God. Sure I come back and repent. But how can I genuinely repent KNOWING I’m going to make the choice to sin/turn away from God again
