I Peter 3: 7-9

That the trial of your faith, being much more precious than of gold that perished, though it be tried with fire, might be found unto praise and honor and glory at the appearing of Jesus Christ:  whom having not seen, ye love; in whom, though now ye see him not, yet believing, ye rejoice with joy unspeakable and full of glory: receiving the end of your faith, even the salvation of your souls.

The battle lines have been drawn.  It is either your faith in Christ or the things of this world.  As our faith grows so will the conflicts in our life.  This is what the apostles warned us about:

I Peter 4: 11,12

Beloved, think it not strange concerning the fiery trial which is to try you, as though some strange thing happened unto you:   But rejoice, inasmuch as ye are partakers of Christ’s sufferings; that, when his glory shall be revealed, ye may be glad also with exceeding joy.

Paul write in II Corinthians 5:19 “Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.”  This passing away of the old things puts us in conflict with the world.
