Romans 8:16 — The Spirit Himself testifies with our spirit that we are children of God.
Jesus died to let us once again enter a loving relationship with our God. Part of this relationship is being a child of God. We are called Children of God so many times that it is undeniable. One of the most famous parables (the prodigal son) talks about this father child relationship. This relationship is so close. Let me explain.
Luke 11:11-13 — “Which of you fathers, if your son asks for a fish, will give him a snake instead? Or if he asks for an egg, will give him a scorpion? If you then, though you are evil, know how to give good gifts to your children, how much more will your Father in heaven give the Holy Spirit to those who ask him!”
Jesus compared our relationship with that of natural fathers and sons. All of the loving things (even common sense things) that fallible, human fathers do are less than what God does to show his love. I recently read a story about a man who had disowned his father (like the prodigal son) and was living a horrible life in order to avoid him. The man said that almost every day his father would come looking for him. Every time the son would ignore his father and leave the door unanswered. It wasn’t until the son overdosed on LSD that they were brought together. The son was in a semi-comatose state for days while his father sat by him repeatedly saying how he loved him. This is the picture of a human father that showed unrelenting love. If this father, though he was evil, knew how to love his son relentlessly, how much more will God love relentlessly. imagine how much greater God’s love is!
God loves us in a way that only He can. His love for His children is unrelenting, unashamed, amazing love!
Galatians 4:6 — Because you are sons, God has sent forth the Spirit of His Son into our hearts, crying, “Abba! Father!”
