This worship instinct rubbed off on Abraham's trusted, old servant. When this servant found Rebekah for Abraham's son, Isaac, the servant worshipped. When Rebekah's parents told the servant that Rebekah could go with him and become the wife of Isaac, again the servant worshipped the Lord. Abraham's son, Isaac, carried on the pattern established by his father. There are more examples, but surely the point is made.
Worship is natural, spontaneous.
Persons in relationship with God respond to God's work and word and presence by worshipping God. They call on the name of the Lord. The NT continues that pattern. Matthew is clear. Notice what characterizes the early church.
