By forgiving others, we tap into that forgiveness, we open the door to it. When we love God and desire to do His will, we are born again, born of the Spirit. It's that simple. Jesus tells us to be perfect. Be you therefore perfect, even as your Father who is in heaven is perfect.
Nobody's perfect, as the saying goes.
Perfection is not our condition, but it is our goal. It will take effort on our part to become more perfect, more spiritual, more like God. There's no time like the present to start. Jesus tells us about God's family. When Jesus uses the term Father, he is talking about his Father and our Father.
