1 Peter 4:7

The end of all things is near. Therefore be clear minded and self-controlled so that you can pray. NIV

1.  The end of the world as we know it is coming;  therefore, it will be more difficult to live as a Christian. Purity (to be clear minded and self-controlled) will help.

2.  Since harder times are coming much prayer is needed—for ourselves and for others. Prayers are more effective when we are pure.

3.  Since the end of all things is near that means that the coming of Christ is near. We must make ourselves pure and ready for Him. Whatever we do for purity now will affect our relationship with our Lord forever.
