Predestination is conditional. If God’s promise to Abraham was foreordained, “In thee shall all families of the earth be blessed God ‘ would not have necessitated God to renew the same blessing to the son. He commanded Isaac ‘Go not down into Egypt..(Ge.26:2).’Interestingly enough God had let Abraham move to Egypt earlier in a similar circumstance ‘when there was a famine in the land’ (Ge.12:10). Consequently Isaac dwelt in Gerar in obedience to His commandment. After Abraham was buried by his sons, God appeared unto Isaac and renewed his promise to his father. It was conditional where faith of Isaac like his father had to match with His faith. It was personal . Misconception of predestination as taught by some sects makes Atonement a feeble copy of God’s glory. For the same reason denying free will would be heresy. We have its perfect example in Jesus. He was God the Son and yet he obeyed God. Free will was not his personal glory but laying it for the greater glory of his Father. He did so he fitted the expression, ‘the Lamb slain from the foundation of the world (Re.13:8)’. So predestination of God is Obedience on the part of the Son for the glory of the father. It must be thus with every one who would be called child of God. Hunting with the dogs may be activism of the evangelicals and on Sundays running with the hares cannot be called as the hallmark of Christians.
In the parable of the Two Sons (Mt.21:28-31) the elder refused to go to the vineyard. His free will allowed him to say no to his father. But he regretted of letting down his father so he went to the vineyard after all. In his obedience he glorified his Father. His younger brother paid lip service to his father but exercised his free will. From this we have the significance of predestination and free will.
