Over the next 15 years or so, David's public reputation grew from obscure child shepherd to well-known child warrior who bravely killed the dreaded Philistine giant Goliath (I Samuel 17:1-51),and as a skilled musician whose anointed playing of the harp drove evil spirits away (I Samuel 16:18-23).
David's harp brought him his first entrance into the throne room (of King Saul), which would someday be his seat of rule (I Samuel 16:14-18). Years later he was crowned king, when he was 30 years old (2 Samuel 2:1-7).
David's rule was one of battle (2 Samuel 8) and one of compassion (2 Samuel 9). He was beloved and he was hated. He was a hero and a coward (I Samuel 21:12). He misused his power to commit adultery and murder, and then humbled himself before God in repentance (2Samuel 12:1-15).
David (tr. Heb. Beloved) was obviously a sinful man, and yet he was chosen by God to be a primary ancestor of the promised Messiah (2 Samuel 7:8-29; Mark 10:47; Acts 2:30). Various aspects of David's life are prophetically and otherwise compared to the life of Jesus the Messiah. Throughout his life David used his musical skills to bring glory to God. The anointing upon his musical gift called warriors to battle, and brought peace. His prophetic songs of joyful praise and warfare worship ring out in churches yet today, proclaiming the greatness, goodness and faithfulness of God.
David was a master musician (Amos 6:5), a poet (2 Samuel 1, 3, 22, 23), a prophet (2 Samuel 23:2),a writer of psalms (Psalm 23), a worshipper (2 Samuel 6:14), a man after God's own heart (I Samuel 13:14), and a"man exalted by the Most High, a man anointed by the God of Jacob, Israel's singer of songs" (2 Samuel 23:1).
The honesty of David's writings (Psalm 22:1) and of his life reveals sin and exalts the righteousness of God. The contrast between his human failures and his effective spiritual life reminds worshipping musicians that God is bigger than sin and shortcomings. The yielded heart of a flawed-by-sin worship leader, song writer, musician or praise and worship team brings an anointing to chase away evil, initiate peace, reveal mercy and truth, cause hearts to exalt the King of Kings, and prepares the way for entry into the very Throne Room of God.
