In The Full Joy Of Jesus Christ Our Lord

When the Believer follow the full instructions of Almighty God. He or she examines themself. After their examination they begin to apply his instructions to their daily lives. By applying the instructions which is the word of God it causes understanding and knowledge which produces wisdom. No more foolish thinking. everything  (meaning every action) has been carefully considered. Before the Believer comes to God he thinks and show the action of a fool.God wants each Believer to be wise and show the wisdom he has supplied unto them by obeying his Holy Spirit.
