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.  

We are to prepare our minds to accomplish whatever God may need us to do. Being prepared and prayed up keeps our hearts active and close to God. It makes it easier to hear from God and get out of the ditches of life. The tests of life don’t seem like mountains when we maintain our focus.
