Psalm 60

It took me about 2 minutes to read this psalm. I'm still pondering the message written down. I see the confession of sin and God presistent adherence to his promise to provide an inheritance in spite of Israel's unfaithfulness. In the last two verses I see the recognition that it is God who provides the courage, it is God who fights the battles, it is God who brings the victory. I wonder if this is a poetic application the Paul's teaching in Romans 8:28?
