When you want your plants to develop into a greater fruitfulness you have to prune it using a sharp knife in cutting off unwanted parts then make sure you apply the necessities that will contribute to improve the production.
Likewise to us if we want to succeed in our spiritual growth we have to read the Bible and pray for God to guide us in putting everything we learn into practice so that we may stand firm in case of any temptations that comes on our way.
Some of us wonder actually what Paul meant in 2 Corinthians 12:7.Paul was having a constant attack from enemies. G. White comments that it seemed to have a problem with his eyesight. Paul believed that his thorn was given to him. He recognized that by nature there is a weakness to sin. In your life have you ever realized your weakness and ask God to develop it through his pruning. God knows our hearts and even our characters better than us.To keep me from becoming conceited because of these surprisingly great revelations, there was given me a thorn in my fresh, a messenger of Satan, to torment me.
