2 Consider it pure joy, my brothers and sisters whenever you face trials of many kinds, 3 because you know that the testing of your faith produces perseverance. 4 Let perseverance finish its work so that you may be mature and complete, not lacking anything. 5 If any of you lacks wisdom, you should ask God, who gives generously to all without finding fault, and it will be given to you.–James 1:2-5 NIV
Why do Christians have to endure trials and persecutions? I suppose people have been asking this question since the first century. The disciples never quite understood why Jesus had to suffer and die until after the Resurrection. God does not allow us to go through suffering so that He will know where we are on our journey, He allows it so that we will know. He allows it so that our “I can” will turn into “No, I can’t but God can”. “No pain, no gain” applies to spiritual growth as well as physical. Would understanding the “why” really make the pain any less real or painful? I am sure that since Jesus was in on the plan of redemption, He understood the why, but that didn’t keep Him from asking His Father if there might not be another way. As he prayed in the garden of Gethsemane.
42 He went away a second time and prayed, “My Father, if it is not possible for this cup to be taken away unless I drink it, may your will be done.”–Matt. 26:42 NIV
It is not a sin to wonder or to question “why?”. It is only a sin when we take it to the point of being disobedient. We need to pray for wisdom, but when we pray for wisdom, we need to understand that acquiring wisdom requires experiencing a lot of things and some of them will be painful.
23 Then he said to them all: “Whoever wants to be my disciple must deny themselves and take up their cross daily and follow me.–Luke 9:23 NIV
