God desires to have a relationship with each one of us as our Father. He adopted us, sealed us with His Spirit, and wants us to be so close in our relationship that we call Him “daddy”. My children always called me “daddy”, and as they got older, they called me “dad”. I would never want a formal relationship with my children. I want them to be close to me and comfortable enough to call me “dad”. Our heavenly Father is the same way. We are now His children, and He wants a close relationship with us. That relationship is revealed as His Spirit communes with our spirit and lets us know that we are His. This is almost too wonderful to comprehend! God has adopted me as His child, and I am now an heir of God! And He wants me to call Him “Dad”.
