Dear friend in Christ, greetings to you in the matchless name of our Lord and Saviour Jesus Christ.
It is very true that everything written in the Bible teaches us something very precious and essential to live a God-willing, God-pleasing life, obviously the best life on this earth and also to reach our eternal home.
The book of genesis records the life of patriarch Abraham. Abraham married (made a covenant with) Sarah and had a son (heir) Isaac at his very old age. Abraham also had another son Ishmael (not heir) through Hagar the slave woman (gentile). There was no way that Ishmael could become Abraham’s heir and so he never shared the inheritance. Later Isaac had two sons – Esau and Jacob the heirs, but Esau could not inherit the blessings. Though God had a plan to bless Jacob as we see in genesis 25:23, there is something we can learn from the life of Esau.
