When the people were cut to the heart and asked John what works must we do,
what did john say?
he didn't give an elaborate list of works
he just said do what is right
and when the people in John 6 asked CHRIST what must we do to do the WORK of GOD?
What did CHRIST say?
Let me give him some references to feed off of: The answer, Dan_473, to miknik5's question is: found in John 6:29. "The work of God is this:
To believe in the One He has sent.
It begins with God's call. We could never even begin to seek God unless he had already found us. The whole initiative is with him; the ground and the moving cause of the whole matter is his seeking love.
It develops in our effort. The Christian is not called to dream, but to fight; not to stand still, but to climb. He is called not only to the greatest privilege but also to the greatest task in the world.
This effort is helped continually by two things:
1). It is helped by the teaching, guidance and example of godly men. God speaks to us through those to whom he has already spoken. "A saint," as someone has said, "is a person who makes it easier for others to believe in God." And there are some who help us, not by anything they say or write, but simply by being what they are, men whom to meet is to meet God.
2). It is helped by God himself We are never left to fight and toil alone. He who gives us the task also gives us the strength to do it; more, he actually does it with us. We are not thrown into the battle to meet it with the puny resources we can bring to it. At the back of us and beside us there is God. When Paul was up against it in Corinth, he had a vision by night in which the Lord said to him, "Do not be afraid...for I am with You" (Acts 18:9-10). They that are for us are always more than they that are against us.
This call and this effort are designed to produce two things:
1). They are designed to produce consecration on earth. Literally in Greek a thing which is consecrated is set apart for God. They are meant to set us apart in such a way that God can use us for his service. The result is that a man's life no longer belongs to him to do with it as he likes; it belongs to God for him to use as he likes.
2). They are designed to produce salvation in heaven. The Christian life does not end with time; its goal is eternity. The Christian can regard his present affliction as a light thing in comparison with the glory that shall be.
