"A sky without clouds can be beautiful, but it would lack the rain that waters the fields so that life flourishes ... A life without challenges can be comfortable, but the triumphs and failures to make sense of existence would be lacking"
Ivan Thompson

Jesus, is the motivator of personal improvement of all times. A character like Jesus:
If God has called you to serve you, it will evidently heal all your wounds, strengthen the fallen areas, once you have gone through the process. Since God wants to bring out the best in you, but the promise is perfect; because in exchange for all this he will give you his glory. To obtain the anointing and the glory of God it is necessary to pay a high price, and be processed to form a character like Jesus'.
There is a biblical verse that I like very much and I apply it to every stage of my life:
"I can do all things through Christ who strengthens me"
