Think about all of the troubles you have endured throughout your life. Think about every single time that life seemed to be too much for you. Now think about every the times in your life when you felt closest to Christ. If you are real with yourself then you must admit to yourself that the two coincide greatly. Pain pushes us toward the Lord. But look pack through your pain and you will see God working. You will see Jesus shaping you into the person that He called you to be.
A shift in focus can shift how you persevere through your trials. Look back over all that God has done in each of your previous vexations. Remember how He came through then. Don’t think so much about your hurt, but look at what God is doing in your hurt. God wants to make you perfect and complete. He is making you spiritually mature so that you won’t be lacking anything that you need. See yourself persevering through pain. See yourself becoming more and more like Jesus. Why? God does.
