We have been tasked with a great work. We are to make disciples. We are to seek His kingdom first. We are to build His Church. Not buildings. Not organizations. People. We are to invest our lives in building up people in the Lord.
We have models.
We can look at the gospels and see how Christ built people up in the Lord. We can read Acts and see how four generations of believers were built. We can read the epistles and see how John, Paul, and Peter continued to work to encourage and build up believers.
That great work has been passed to us. As David provided the materials for Solomon, so we have been provided the materials by the Son of David.
It is a great work.
