I believe the answer is yes. With God’s help we can indeed live this kind of life. It is possible. I am not saying we will never make another mistake. While we live in these human bodies we will always make mistakes and have to ask God for forgiveness. But God expects us to live as good as we possibly can, with His help.
We do need to watch our conversations because people listen to how we talk when we claim to be a Christian. They expect us to talk different. What do people hear when they listen to us talk? Is it something that would attract them to Jesus? We need to live as close to God as we possibly can. It is so important that the world see Jesus in us. If they don’t see them in those that claim to be His, how are they going to see Him?
