Then they said to him, "What must we do to perform the works of God?" Jesus answered them, "This is the work of God, that you believe in him whom he has sent." (Jn 6:28-29; NRSV)
It sure seems like there are a lot of people out in the world who believe "works" alone will get them into heaven, that's just not so. Jesus said, "This is the work of God, that you believe in him whom he has sent." Once we believe in him, we want to do other "works," not because they save us (which they don't) but because we want to do good for others out of the love we have found in Jesus.
When we become Christians, we do not want to do these "works" for our own benefit, but out of love. This love is the same love that caused Jesus to touch lepers. He touched them, which made him unclean. He didn't touch them to glorify himself but to show them true love and compassion. He didn't think of himself but only of the other person and how he could help them. This same love caused him to weep over the grave of a friend and to raise him from that grave to life again. This same love was shown when our Savior went to the cross to die for me, to take my place, again, not to glorify himself but because he loves us that much.
So, what are the works of God that we are to do? "Believe in him whom He has sent," and then the works will not be because of ourselves but because of the love and compassion we have learned while sitting at the feet of Jesus.
