1 Timothy 4:8-12

For bodily exercise profiteth little: but godliness is profitable unto all things, having promise of the life that now is, and of that which is to come.

This is a faithful saying and worthy of all acceptation.

For therefore we both labour and suffer reproach, because we trust in the living God, who is the Saviour of all men, specially of those that believe.

These things command and teach.

Let no man despise thy youth; but be thou an example of the believers, in word, in conversation, in charity, in spirit, in faith, in purity.
