Why did God allow evil in this world unless He knew that we had something really important for us to experience. Jesus gave us the answer to this in His parable of the prodigal son, Luke 15-11 to the chapters end. Since this is representative of someone who was lost in the world but forgiven and received back by the Father, Jesus has given us this lesson to show what happens to the person who has been forgiven. This Father who let His child leave the comforts of home knew one major value that the remaining son could not value-appreciation. Nothing changed for the son who stayed, but to the son who lost everything learned to value those things he lost, but were later restored. This is like us not valuing the need for a doctor until we become sick. We can't value forgiveness until we fall. We can't really value how much more that it appears that God loves us since we had fallen. God knows this and has allowed evil to exist because the new birth is worth the pain and the wait, John 16-21. This is like a similar parable that I heard: When do you know the strength of a soap cleaner but when you have washed something clean, or the most dirty thing that you can find. Jesus is the soap.What is most difficult to understand is how anyone is able to confuse our being foreknown from this age when we come to God and He saves us by the Blood of the Lamb.
What is even more difficult to understand is how anyone coud think of a lving heavenly Father Who would subject His children to this age and all the pain and suffering it contains knowing full well in advance just what they would do and how they would react to Jesuchrist.
This latter describes Satan and not our Father Who loves us and is allowing us to choose to come home to Him.
When do you value a feast the most, after you have just eaten, or when you have not eaten at all. Your value for something which does not change is valued the most by our distance from it.
We could not value the gift of salvation and love until we first suffered distance from Him, that love being eternal for us. Evil is designed to be done away, and all will be restored.
