Do you believe this?
Followers of Jesus still experience life, the good and the bad. We will still die. We will still get sick. We will still experience hardship. This is all part of being human. The flip side is true too. We will experience periods of incredible happiness. We will experience times of such quick answers to prayer that we will be in shock at God's goodness.
The difference between a follower and a nonfollower is that God makes it all good if we let Him -- and He listens to our prayers. AND, we will see impossible situations become possible through Him (not to mention the sweet fellowship we can have with God constantly -- that's the best part).
So, what are you struggling with? What is that one area that constantly is a thorn in your side? It is most likely impossible for you.
But it isn't for God. There is nothing, nothing, absolutely nothing that is too hard for God.
Why haven't you let it go yet? Why do you hold onto it so tightly? Why have you gone through the motions of letting it go but continue to hold onto it within?
Let God show you the reasons behind your grasping -- then let Him help you wholly release it so He can work.
