Commentaries:
God judges true Christians today by how well they live by His Word, and He will judge those who rise in the second resurrection exactly the same way. They will be given enough time to live a life of overcoming and obedience, just as God's firstfruits are doing in this age.
Martin G. Collins
Holy Days: Last Great Day
This passage begins by seeming to say that God sends only the ministry to labor in His behalf. However, as Paul proceeds, the context reaches out to embrace all the called of God by admonishing us to take heed how we build the Temple, the church of God. I Corinthians 12 leaves no doubt that we are all members of the Body of Christ, and it is the Body of Christ that is sent forth to witness for God in the world. The Body of Jesus Christ is the Israel of God in this New Testament period (Galatians 6:16).
