You repent. Honest, heart and bone deep repentance. You accept the Lord into your life.
Guess what.
It ain’t like buying a lightning rod. One purchase does not make you safe for both life and the hereafter.
You still have to check it is grounded, that it is the tallest part of your property (soul) and still, lightning may strike some other part of the house.
Every last thing you do must be examined under the commands of the Lord. No evasions, no “good intentions” (we have been told where they lead!) just under the Word.
I bought a lightning rod when I accepted the Lord into my life. I failed to maintain it and got struck hard because I did not maintain it.
I blamed Him. The one who gave me the lightning rod, not the idiot who put it up and forgot that it requires maintainence.
Look for the fruit. If one is repentant, it is an ongoing battle to overcome those fleshly desires.
Our earthly fathers, while not perfect, are a picture of our heavenly father. I messed up several times growing up, but I was never tossed out of the family.
Better example. My pastor has adopted a child. That child is now a permanent member of the family. When I confessed that I was a sinner and needed Christ as my savior, I was adopted. One of the fruits of that is that I daily fight against my sinful desires. I will fail from time to time, but I am not going to be tossed out, I cannot lose my salvation, as I see it for the gift it is, and desire to please Him who saved me. His sacrifice was not a “get out of hell free” card that allows my to continue sinning.
One who has me desire to repent was most likely not really adopted into Gods family. If there is no true desire to be member of Gods family, god does not force you.
