See, the Sovereign Lord comes with power,
and he rules with a mighty arm.
See, his reward is with him,
and his recompense accompanies him.
He tends his flock like a shepherd:
He gathers the lambs in his arms
and carries them close to his heart;
he gently leads those that have young. Isaiah 40:10-11 (NIV)
The only moral purpose of strength is to lift up the weak.
