It's your devotion that will define you

O God, you are my God; earnestly I seek you; my soul thirsts for you; my flesh faints for you, as in a dry and weary land where there is no water. - Psalm 63:1

There are many things that God could have chosen to define the life of David. He could have chosen to sum David by his mistakes. He could have said:

David a..... murder
David an.....adulterer

But he chose

David a.... man after my heart
David a.... man of devotion

After removing Saul, he made David their king. God testified concerning him: ‘I have found David son of Jesse, a man after my own heart; he will do everything I want him to do.’ - Acts 13:22

Billy Graham said:

You cannot possibly be a happy, dynamic, and powerful Christian apart from a daily walk with Christ. Christ is calling Christians today to cleansing, to dedication, to consecration, and to full surrender. DEVOTION will make the difference between success and failure in your spiritual life. It will make the difference between being helped and helping others. It will make a difference in your habits, in your prayer life, in your Bible reading, in your giving, in your testimony, and in your church membership.
