You're going to have a period in your life where it seems like things aren't working. You're going to have doubts, trials, tribulations, and challenges. You're going to have turn-back moments but you have to make a decision to keep going.
If you are trying to get through life without God, YOU ARE TRIPPING! YOU NEED GOD! When you call on God, he gives you the tools to handle the peaks and valleys in life.
