If you are a reader of the bible, you notice something about Jesus. He challenged all that surrounded him. He constantly taught, healed, led, scolded. But on his "down " time. The time when he was alone. The time when he just needed some space. He prayed. And he prayed extensively. We in our busy world can definitely take a cue. In our down time we need to meditate on the Lord. There is no other way that peace will rack up rewards as to praying to our almighty God.
Therefore, since we have been justified through faith, we have peace with God through our Lord Jesus Christ, through whom we have gained access by faith into this grace in which we now stand. And we rejoice in the hope of the glory of God.
