Just because you are christian does not mean that you are excluded from pain and heartache. As long as you are living on this earth, sorrow is unavoidable. There's a battle going on between good and evil, and satan is not happy with anyone that is following Christ. It is his sole mission to separate you from the Savior of the world. He doesn't care how he does it just as long as he succeeds. The devil wants to make sure that you won't make it to heaven. Perhaps the death of a loved one has shaken your faith, or your heart was broken by someone you trusted, or you received an unfair sentence. It is at your weakest moment that the enemy tempts you to blame God, but it's not God's fault, nor is it His desire that anyone should suffer. Whatever your trial or pain, you are suffering, don't play the blame game and tell yourself it's all God's fault. It's not. Pain and heartache is the direct result of sin, and it won't be a perfect world until Jesus comes. Don't allow satan to rob you of eternity, instead, run to the open arms of Jesus for comfort, guidance, and peace. God will walk with you through the valley and replace your tears with His joy.
