If you find yourself getting distracted or are having problems staying on course you simply need to change your focus from the temporary things (earth) and set your mind on things above (eternal).
Wrap your mind around the great truth of what God accomplished on the cross of Calvary. He poured out His infinite love so that we may enjoy eternal blessings. We have unlimited riches in Christ. We will have an eternity to explore the riches of Christ and will never exhaust the supply. Imagine that!
Contemplate on that and you will find yourself steering a straighter course. Phil 4:8 Finally, brethren, whatever things are true, whatever things are noble, whatever things are just, whatever things are pure, whatever things are lovely, whatever things are of good report, if there is any virtue and if there is anything praiseworthy–meditate on these things.
