Matthew 12:50 For whoever does the will of My Father in heaven is My brother and sister and mother.
There is no way we can be so obedient and righteous as to be able to follow the will of God, but having the heart to want to do so is what God is looking for.
It is God in Heaven who is watching and allowing us to learn all we need to know about Him. He sent Jesus down to us to be the interaction we needed to fully learn His will in our lives.
God looks on us as brothers and sisters because we are willing to try and do His will every day of our lives.
