A question you may be asked when witnessing is, “How can there be any benefit to all the suffering in this world?” While God may not give us a complete answer in this life, here is an illustration that you might use when responding to this question.
Suppose Adam and Eve were still in the Garden of Eden before the fall. They lived in perfect conditions and in perfect fellowship with God. One day people from our fallen world were allowed to enter their paradise. When these people meet Adam and Eve, they begin to cry with wonder, “It’s perfect here – everything is so beautiful!” To which Adam replies, “Yes we like it.” “No, you don’t understand, this place is wonderful beyond description, you have pure love with God and one another, there’s no pain or sickness, just fullness of joy!” To which Adam replies, “Yes, we agree, it’s nice here.” The visitors persist, “You don’t understand Adam, there is no loneliness, no hunger, no misery at all, only a river of holy pleasures and indescribable communion with God.”
You see without a reference to compare to, Adam and Eve could not comprehend how wonderful their paradise was. Only those who have suffered can fully appreciate heaven. The Bible reminds us: “For our light affliction, which is but for a moment, is working for us a far more exceeding and eternal weight of glory.” Ultimately, when we see God, we will agree that all His ways are true and righteous after all.
