Have you ever wondered why some Christians won't attempt anything remotely substantial for God? After reading the parable of the two sons in Matthew 21 v28-32. The only conclusion I came to is that "some will, and some wont!"
Jesus tells the parable of two sons who were given clear instructions by their father to go work in his vineyard.
The first son was reluctant to work, but afterwards came to his senses and did as his father had asked him "I will not: but afterward he repented, and went"
The second son initially showed promise! But decided not to go work in the vineyard "And he answered and said, I go, sir: and went not"
Jesus Christ finishes this parable by asking the listeners "Whether of them twain did the will of his father" - the answer clearly being the first son. The parable was spoken to contrast how the scribes and pharisees rejected the teachings of John Baptist un-repentantly, but the publicans and harlots gladly received the teachings are were saved
"For John came unto you in the way of righteousness, and ye believed him not: but the publicans and the harlots believed him: and ye, when ye had seen it, repented not afterward, that ye might believe him"
The parable itself can be interpreted though for Christians who have been given clear instructions to go "work" in the vineyard of our heavenly father. Let's say the command is the great commission "Go ye into all the world, and preach the gospel to every creature"
This command is clear, but the response by all Christians will be one of two things! Some will obey and do, and some won't obey. There could be a plethora of reasons behind their decision but it will always be that some will and some wont.
I have come to two conclusions from this simple truth; and they are these.
1) Thank God that we are not saved by our "works" but rather by the blood of Jesus Christ. Reason being if we were justified by our works, then we all would fall short, even if we were to obey every command of God, we will fall short of perfection every single time. Jesus Christ on the other hand did all that was required of him, and died as the perfect sacrifice for our sins. The works we do show our love for our father, but do not justify us in is sight and they never will. Only Jesus Christ can justify us through faith.
2) Don't be downcast when you see Christians around you not wanting to do anything for God, but you yourself are trying to live a righteous life or trying to preach the gospel to others. God know's and see's the everything and someday we all individually as believers will have to stand before God. This will not be for judgment of our sins, since we have been declared righteous already, but rather it will be to give an account of how we lived our lives here on earth. Whether we spent out time laying up treasures in heaven or spent our time building up wood hay and stubble here on earth.
