"Jesus answered and said unto them, This is the work of God, that ye believe on him whom he hath sent." (John 6: 29)
When I heard this verse, I was first relieved, then more distressed.
If the only "work" is to believe on Him, then what am I supposed to do?
This conflict creates the greatest problems for us. We try to live "The Christian Life", as if Jesus Christ merely came to give us "some help".
"Doubting" Thomas voiced this error, and Jesus corrected Him with the truth, and Jesus Christ could not have been clearer:
"5Thomas saith unto him, Lord, we know not whither thou goest; and how can we know the way? 6Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me." (John 14:5-6)
Jesus did not come to give bad men steps to become good men. He did not come just to die for our sins. He came to give us His life, and to live through us:
"16For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life." (John 3: 16)
"Behold, what manner of love the Father hath bestowed upon us, that we should be called the sons of God: therefore the world knoweth us not, because it knew him not." (1 John 3:1)
"In this was manifested the love of God toward us, because that God sent his only begotten Son into the world, that we might live through him." (1 John 4: 9)
We believe on Him, and then He lives through us.
