A cheater will always be a cheater. And if the other woman thinks she's got him and he is faithful to her, she is delusional. I have his messages and videos that he sends me to prove it. He is still cheating on her.
2 Corinthians 12:9 But he said to me, “My grace is sufficient for you, for my power is made perfect in weakness.” Therefore I will boast all the more gladly about my weaknesses, so that Christ’s power may rest on me.
