Why was David a man after God's own heart?

Psalm 63:1-3 (New King James Version)

¹ O God, You are my God;
Early will I seek You;
My soul thirsts for You;
My flesh longs for You
In a dry and thirsty land
Where there is no water.
² So I have looked for You in the sanctuary,
To see Your power and Your glory.
³ Because Your lovingkindness is better than life,
My lips shall praise You.

Ponder this: I noticed 3 things in the above scriptures that will help us understand why David - the adulturer & murder - was a man after God's own heart.

vs1. David purposed in his heart to seek the Lord. "Early will I seek you." David did not squeeze God into his schedule but he alloted a special time in his day where his only priority would be to seek the Lord.

vs2. David saw God's glory. When a person in the Bible saw the glory of God like Ezekiel, Isaiah or Moses, their life shifted. God became so real to them through the revelation of His great glory that they were now even more willing to serve the Lord and lay down their lives for Him.
Do you have any fear of anything at all? One should seek to see the glory of the Lord so that ALL FEAR, however minute it may be, will shatter before the presence of the Lord. I guaruntee that your life will never be the same again.

vs3. David loved God more than his very life. Can you say right now that you could live a reasonably happy life without God? Can you say right now that you could live without God but your life would totally come to ruin? Or can you say that if you didn't have God in your life, you would literally die? David choose death over the abscence of God.

This is a man, who was after God's own heart. How does your heart compare?
