Hebrews 12:11-13

For the time being no discipline brings joy, but seems sad and painful; yet to those who have been trained by it, afterwards it yields the peaceful fruit of righteousness [right standing with God and a lifestyle and attitude that seeks conformity to God’s will and purpose]. 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.
