You don’t have to rely on your own strength. You’re relying on God’s strength. Trust in His righteousness, sacrifice, love, and power, not your own. I feel like this relates to my other Advent post from today.
Also this, from Isaiah:
Trust in the LORD forever!It is trampled underfoot by the needy,
For the LORD is an eternal Rock.
He humbles those in high places,
and the lofty city he brings down;
He tumbles it to the ground,
levels it with the dust.by the footsteps of the poor.
