"I'm here to PUMP, YOU UP!"
Psalm 121:1
I look up to the mountains; does my strength come from mountains? No, my strength comes from God, who made heaven, and earth, and mountains.
Sometimes we look for strength in ourselves, and we can't find any! What we must realize is that we are looking in the wrong place. Our strength, real strength, comes from God alone, our creator.
Muscles don't match up to the power of God. I have seen large men fall apart in trouble times while small women rise up with a sense of power within because they know where their strength comes from.
When you are facing something that makes you feel weak, then rely on God's strength to get you through.
