When a person becomes a Christian, that person establishes a relationship with God. Scripture verifies a relationship comes into existence by using specific concepts. All this growth occurs within the context of a spiritual family. God is the Father. Jesus Christ is the oldest brother.
Christians are brothers and sisters to each other.
There are two defining realities at work in every person who is a Christian, each person who is in God's family. The first defining reality is spiritual growth. We do not all begin our spiritual growth at the same point of spiritual development. Just as some infants physically are born with serious problems, some Christians are spiritually born with serious problems. The birth occurred, he or she is God's child, and it is unthinkable that we should abandon this spiritual infant, but the problems are real.
