We all know the story about David and Goliath. Goliath was a big giant who was "talking smack" about the God's people and God. Sometimes, we think that was the whole story, but it wasn't just that. David had other giants in his life. He had the jealousy and disdain of his brothers and the fear coming from his fellow men (the army). He was just a little shepherd that wanted to do something about it.
So what was his cause. He told Saul in his conversation. He said "seeing he hath defied the armies of the living God." Saul, wake up! A big bully is threatening to destroy your army. In doing so, he is defying your God. Are you going to show him how big your God is? Instead, Saul was trembling in fear. When we are shaken and scared, remember, we make our God look very small.
Proverbs 3:5-6 says "Trust in the Lord with all thine heart; and lean not unto thine own understanding. In all thy ways acknowledge him, and he shall direct thy paths." ...and this is what David did. THERE WAS A CAUSE, the cause was God.
What was his weapon?
I Samuel 17: 45-47 Then said David to the Philistine, Thou comest to me with a sword, and with a spear, and with a shield: but I come to thee in the name of the Lord of hosts, the God of the armies of Israel, whom thou hast defied. This day will the Lord deliver thee into mine hand; ... for the battle is the Lord's, and he will give you into our hands.
I want you to get this. There is a cause.
The cause is God getting the glory.
The cause is showing how great our God is.
The cause is showing people the love of God but also the justice of God.
Ultimately, the cause is showing people the cross.
The cause is there. What are you going to do about it? "...the battle is the Lord's" He's going to fight with you. Will you take up His cause? - Rejoicing in the Present
