He was mad at his loss of money due to government actions. He felt his life was not worth living, so first he blew up his house with his wife and child inside (who escaped harm), then flew his plane trying to kill even more people. He was of his father the devil. This man flew himself straight into Hell for all eternity!
Saints as the children of God, our life is always worth living, even though it may get tough at times, God is working something out in us, for our eternal benefit, during those tough times.
Our lives should not consist in the abundance of our possessions, because our lives are hid with Christ in God. We should not measure the value of our lives by the amount of happy days we have, but in the fact that God is keeping us alive for His purpose and for His glory.
There is always some brother or sister who is walking and even harder path than we are, and we must Praise God even in heaviness of spirit. We must remember that God is our deliverer, our High Tower, and our ever present help in times of trouble.
Unless our security is in Christ in this hour, we will fail and we will fall just as this man.
