From Lyca Fagela:
One day, God had work for me to do. He showed a rock and told me to push it with all my might. For many years, I pushed and pushed but nothing happened. The rock hasn’t moved even an inch. In discouragement, I asked God why am I failing. The Lord responded: “Your task is to push the rock. Never did I mention that you move it. Now I, my child, will move the rock.”
Obedience to God is easy if we only know how to listen. He doesn’t want us to suffer, He only wants us to learn.
