Around a week ago I had a friend ask me, how do you stay happy in a world like this? His point was in the midst of all the chaos in this fallen world it sure is hard to stay afloat. I basically said to him that he was right, this world is fallen. Its not going to be perfect. We are sinners, rebels against God, so this world will not give us complete happiness.
On the other hand, I explained to him what keeps me going in the midst of the chaos. And it is this: The fact that Jesus, the eternal God, came to live on this earth for me. The fact that he lived a perfect life to give me righteousness that I so desperately need, that he died for me and rose again for me. (2 Cor. 5:21, Philippians 2:6-8, 1 Peter 1:24).
Every day we must come back to the gospel for encouragement. It is seeing and savoring the objective truth's of the gospel that keep us going. When we sin or when we see sin around us we must remind ourselves of our sinfulness, but also delight in the fact that there is a Redeemer-Jesus God's son. And put our trust in him, for he will come back to this earth again to judge unrighteousness.
