God is a Father.
The fact that God is a Father is proven by His loving actions toward His children throughout history; first the Israelites, then the Israelites and the Church. We also see proof of His fatherhood in the way His one and only Son, Jesus Christ, referred to Him. Jesus almost exclusively called God “Father”. One of the only times Jesus called God “God” is when He was near death on the Cross and God was forced to forsake Him because Jesus had taken all of mankind’s sin into Himself (Mark 15:34).
It is God’s Fatherhood that answers the question, “Why did God create the earth and man?”
He created mankind so He could have a family. There are people who take offense at this answer. They say, “Is God so vain that He needed to create people so He could have something to praise Him?” Nothing could be further from the truth. God does not need our praise, but He takes great delight and we find our purpose in it.
God wanted a family so He could pour His love and blessing out on them. All throughout scripture we see God making promises to bless His children and faithfully fulfilling those promises.
He gave Adam and Eve dominion over the Earth to subdue and cause it to flourish (Genesis 1:26-28). This promise continues even today.
He brought Abraham out of his home country, greatly blessed him with livestock and servants, and told him that his children would be as numerous as the stars in the sky or the sand on the seashore.
God promised King David that his throne would continue on forever. It does even now through the Lord Jesus Christ.
He promised to save all of mankind from their sins and sent Jesus to die on the Cross and rise again in order to fulfill that promise.
All of God’s works since before the beginning of time have been motivated by His loving Fatherly heart.
“For you have not received a spirit of slavery leading to fear again, but you have received a spirit of adoption as sons by which we cry out, “Abba! Father!” The Spirit Himself testifies with our spirit that we are children of God, and if children, heirs also, heirs of God and fellow heirs with Christ,” (Romans 8:15-17).
When we open our eyes to see this beautiful truth, confusion about who we are and why we’re here will fall away. We will realize that God’s greatest desire is fulfilled by having a relationship with His sons and daughters and our greatest desire is fulfilled by having relationship with our Heavenly Father.
