As long as we are cruising along, we have everything under control and we can handle it. We are not depending on God. So, one reason God allows suffering is so we will depend on him. I didn’t say God causes suffering, but he allows it. Here’s another reason, because suffering shows us the value of God’s grace. Sometimes, we think grace was just something way back yonder when we got saved. It was grace that brought about the forgiveness of our sins, but we forget that God’s grace is active right now, present tense.
