Jealousy and God's Love

Jealosy over the gifts of God is a sign of spiritual immaturity.  If we are joined to God, then we are joined to those who are also joined to God.  If we are joined to those others as part of one body and spirit in God then how can we be jealous?  We are all part of a whole, there is no need to be jealous, is the eye jealous of the ear because it can hear?  I get jealous but I am working hopefully toward joining with God and this is a sign for me to look for that I am there.  I am not there yet.
