If you want to become a man after God’s own heart you have to examine the men in the Bible whom God both chose and loved and imitate them.
David was a man after God’s own heart. How did he live his life? David meditated on God’s word. We know that from the Psalms. He was courageous as evidenced by his fight against Goliath. He was unafraid to confess his sin and ask for forgiveness when confronted by it. 1 Kings 15:5 KJV says, Because David did that which was right in the eyes of the LORD, and turned not aside from any thing that he commanded him all the days of his life, save only in the matter of Uriah the Hittite.
Job was also a man after God’s own heart. Job 1:1 KJV tells us, There was a man in the land of Uz, whose name was Job; and that man was perfect and upright, and one that feared God, and eschewed evil.
Paul was chosen to preach God’s word to the Gentiles. His zeal was evidenced by the trials he went through. He was stoned, beaten with stripes, ship wrecked, yet he didn’t give up. He didn’t waver. He kept preaching and teaching the Word of God.
This is by no means an exclusive list of the men God loved and chose to do his work and keep his word. Nor is it an exclusive list of things you should do if you want to follow the Lord.
Read the Bible regularly, pray for wisdom and understanding, and live out God’s word as you learn it. Just as women should dress conservatively I believe men should dress conservatively. As a man do not cover your head when you pray to the Lord. Don’t be effeminate. These are just a few nuggets from Church tradition and the Bible on how to become a man after God’s own heart. Another crucial thing is to build a relationship with God. Keep his commandments. Read the Bible. Pray. Attend Church. Living our these things will become easier as you go and God himself will help. Draw nigh to God and he will draw nigh to you. James 4:7-8.
