My son, do not despise the Lord's discipline or be weary of his reproof, for the Lord reproves him whom he loves, as a father the son in whom he delights.
For the moment all discipline seems painful rather than pleasant, but later it yields the peaceful fruit of righteousness to those who have been trained by it.
Therefore, preparing your minds for action, and being sober-minded, set your hope fully on the grace that will be brought to you at the revelation of Jesus Christ.
For while bodily training is of some value, godliness is of value in every way, as it holds promise for the present life and also for the life to come.
Or do you not know that your body is a temple of the Holy Spirit within you, whom you have from God? You are not your own, for you were bought with a price. So glorify God in your body.
