As someone who is working with others in the Word of God, it does not matter what I know. It matters that those with whom I work are equipped to see more than they have in the past, and by extension see things that I have not seen. That is the genius of Ephesians 4:11 – 16. The gifts are given to build up the others in the body to fulfill their place in the body. In so doing those who are being built up build up those who initially helped them. Paul referred to this in Romans 1:12. He expected to be ministered to, to have his faith strengthened by the Roman believers when he was able to finally come and minister to them.
That is true with those who we help. It is also true for our kids. They will grow to build us up. If we are doing our job.
