Hebrews 12:12-14

So then, strengthen hands that are weak and knees that tremble. [Is 35:3] Cut through and make smooth, straight paths for your feet [that are safe and go in the right direction], so that the leg which is lame may not be put out of joint, but rather may be healed. Continually pursue peace with everyone, and the sanctification without which no one will [ever] see the Lord.
