The very foundation of Christianity is faith. It takes great faith to believe God, that we’ve never seen, sent his son, Jesus, to die on a cross for us. Our faith is what gives us the assurance that even though we cannot physically see God, he is with us. Our faith gives us the strength to push through the difficult times when it seems that everything on earth is caving down around us.
Moses killed a man and ran to hide. Rahab was a prostitute. Noah got drunk and then was found naked. These are our heroes of faith. Why do you suppose God put this in the story? God can use us despite our pasts. He can use us in spite of ourselves. Praise God that nothing we could ever do would separate us from the love of our Father. God can and will still use you for great things.
Our God is a good, loving Father. We often struggle to believe that our faith is enough. We struggle to grasp that our faith plus nothing equals our salvation. We think if we work harder, pray harder, attend more church events, that God will somehow love us more and be more pleased with us.
