Sometimes we have doubt. We think how could God think this is okay? Or how could God let this happen? We don't like to admit that we sometimes let these doubtful thoughts cross our minds, but we do. And it is okay- as long as we take time to remember what is actually happening when it seems like evil is winning.
God is not plan B. Jesus was not plan B. Think of all the times in the Bible when it seemed like things could not be going worse- I mean Jesus was beaten and crucified. But that was God's plan from the beginning. There were no "mess ups" that led him to that plan. It seemed like, in that situation, that evil was definitely on top, but it was not. God's plan is always perfect, and He is always in control- no matter how the situation may seem.
Hard times will come. While His plan is perfect, He does not promise us smooth sailing. So, we must equip ourselves with how to handle tribulations.
We have to trust in Him and His plan, no matter what. We have to realize that even if we don't see the end results being optimal- it is all apart of His perfect plan for our lives.
We must also do good. When it seems like evil is prevailing, we must be the light, show that we as Christians are different. Good is a must for the destruction of evil, and we must let Christ's goodness and love be shown through us.
Trials will come. Evil will seem like it is winning, but we must be steadfast in our faith, trust His plans, and commit to Him, and He will always triumph.
