1 Peter 1:13

So prepare your minds for action, be completely sober (in spirit-steadfast, self-disciplined, spiritually and morally alert) fix your hope completely on the grace (of God) that is coming to you when Jesus Christ is revealed.  

As believers, are we prepared for action? Are we prepared to talk to the sinner about salvation or pray for the sick? Are we ready to walk on water when Jesus calls us out of the boat? When we keep ourselves engaged in the word, go to church, and obey God, we will be ready when called into action.
