For the grace of God that brings salvation has appeared to all men,…
They are zealous because —
1. The spirit of the work is in them. A disposition, a bias, a zeal, consonant with the nature of the work, whose relation to God makes it a good work, is implanted in them, and they have naturally a pleasure in its performance.
2. Christ's command is that they should so act that they should bring forth fruit unto His glory. His commands are precious to them because they love Him.
3. In the performance of good works the Christian finds his daily support. The way of good works is the way of salvation, and there abound its consolations.
4. In the way of good works the people of God obtain fellowship with God. Here are the shinings of His face. It is here that darkness turns into light before them. It is here the Lord speaks to His people, and where He strengthens their hearts against folly. It is in the ways of holy exercise that "the God of peace" is with them. These are the "galleries" in which the King is held. Truly here "our fellowship is with the Father and with His Son Jesus Christ."
