“How do I heal from a guilty conscience?”

1 John says we need no one to teach us, but God gave us pastors and teachers. I don’t get it! What do you think about the horrible things that are happening around the world? Is the return of Jesus getting nearer? Which book would you recommend to grasp the basics of God‘s grace? Why does Paul say leaders should be husbands of one wife? How do I heal from a guilty conscience over my sins? Do you think the war in Gaza had to happen for Christ to come back? Please pray for my son: he wants to get back with his ex-wife, but she has already remarried!
