Psalm 108:13 Through God we shall do valiantly: For he it is that shall tread down our enemies.
Amazingly we want to take credit for the great things that God is doing. We think somehow that it is our bravery and courage. We think that we have won victories. This verse makes it clear that it is the Lord. He is the One that is accomplishing great things.
This verse should give us confidence that we can go out and do the ministry He has put in front of us. We know that it is not about us but about Him. We know that it will be God getting the victory so we can attempt great things for God as we expect Him to do great things through us.
