“He that is of God heareth God’s words: ye therefore hear them not, because ye are not of God.” John 8:47
Jesus was spending time telling the religious leaders of their unbelief. They claimed to love Moses and the Law; also claiming to be children of Abraham. Though they were biological descendants of Abraham Jesus was confronting them concerning their spiritual connection with Abraham. They had none.
The message from Jesus for us today is this. Just because you were born in a Christian household does not make you a Christian. A friend of mine once told me this, “God does not have any grandchildren.” Those who believe in Him through the death, burial, and resurrection of His Son Jesus are sons and daughters of God – born again by grace through faith (Ephesians 2:8-10).
The evidence you are a child of God is clearly explained in Jesus’s words above. We hear His word and do them. We believe His word and put them to work in our lives.
How about you? Have you been born again? Do you believe the word of God concerning what He has said about Jesus His only begotten Son? If you do not, then you are not a child of God, but a child of wrath, and doomed eternally.
You can call on the name of Jesus right now, turning from sin and unbelief, to the Lord Jesus Christ believing Him.
