My Original response which includes a point by point discussion of this pastors comments were 9 pages long. I don't think anyone wants to read all 9 pages at once (if you do email me and I'll be happy to send it to you). I've decided to break it down into sections to make it easier. Here is part 1.
I. IT IS A LAW OF NATURE THAT THE REAPING SHALL CORRESPOND TO THE SOWING.
This is part of the general law that, other things being equal, the same cause always produces the same effect. There is no known exception to the law of causation; there is no possible evasion of it. We see it plainly working in human affairs. The eternal constancy of nature assures us that the consequences of which certain conduct is known to be the cause will undoubtedly follow (sin, relationships, health, career, finances).
My initial concern is that you start out by relying on an observation of nature rather than the Bible. I would like to believe that we should start with a Biblical foundation and move on from there. Wouldn't you agree?
Although there are many metaphors we can take out of the Old Testament I do not believe it is proper hermeneutics to form a whole doctrine on them without having Jesus or the Apostles make the point somewhere in the New Testament as well.
The special law of sowing and reaping is that the product of the harvest will be the same in kind as the seed sown. Tares will never produce wheat, nor wheat tares. But each seed reproduces its own kind. This is seen in human affairs. Commercial industry tends to commercial wealth, intellectual study to a state of intellectual culture, etc. It is vain to think that money will buy refinement or that learning is the road to wealth. Each pursuit has its own consequences in accordance with its own nature; finances are included in this principle both naturally and spiritually.
I have to stop and ask a question at this point. What is your definition of grace? I believe you would say it is "unmerited favor", correct me if I am wrong. I bring this up for obvious reasons:
Romans 6:23 "For the wages of sin is death…" (i.e. when you "sow" sin "you" reap death), "…but the gift of God is eternal life in Christ Jesus our Lord."
Ephesians 2:8-9 For it is by grace you have been saved, through faith-and this not from yourselves, it is the gift of God- not by works, so that no one can boast. (i.e. we sow sin yet reap life).
How do you see these verses in relation to the "Law of Causation"?
The way I see it, these two scriptures alone refute that "law" and also show the beauty of Christ's message. We must rely on God to save us, despite what we sow. You can sow all the goodness, kindness, finances, time, love, joy, whatever and in the end you will reap death… unless Christ saves you. Isn't this the essence of the Gospel of Jesus Christ in which we both strongly believe?
II. THIS LAW APPLIES TO SPIRITUAL SOWING AND REAPING.
- Here the future depends on the past and present by a certain law of causation. No words could more plainly assert that our conduct is shaping our own fate; and these are not the words of James, but of the Apostle Paul, and they occur, of all places, in the Epistle to the Galatians, where the doctrine of justification by, faith is most vehemently asserted! Moreover, they are not addressed to Jews still under the Law, nor to heathen who have not yet availed themselves of the privileges of the gospel, but to Christians who have come into the justification by faith, as it is to Christians that St. Paul says elsewhere, "We shall all stand before the judgment-seat of God" (Rom. 14:10). We are here reminded that the future consequences of conduct are natural, not adventitious-that they are caused by what we are and do, that they flow of their own accord from our lives, and are not assigned from without by any arbitrary decree. We simply reap what our own sowing has produced for us.
Another scripture to look at:
Romans 3:23for all have sinned and fall short of the glory of God, and are justified freely by his grace through the redemption that came by Christ Jesus.
Justified freely, I love to hear those words; they tell me the gift is free. Christ, through his work of grace on the cross, has overcome both the laws of nature and the law of causation.
You can also look at it from the other side. Christ "sowed" a perfect life and yet he "reaped" death, mocking, and torture. This should also show that while the "law of sowing and reaping" may be a natural principle, those that believe in Christ are not necessarily bound by "the natural". Actually, salvation and our walk of faith with Christ is a supernatural life from beginning to end.
Also, look at the lives of the apostles. Many went through all kinds of trials and tribulations, despite sowing all kinds of wonderful seeds… why do you think God put them through this?
These are all exceptions to your Rule of Causation and, in my opinion, this Biblical thinking of God's grace through the cross destroys the seemingly airtight logic of "Tares will never produce wheat or wheat tares but each seed reproduces its own kind". Was the rejected, beaten, and crucified Jesus, therefore, a "tare" because He reaped suffering and death?
When we look at it closely, the Law of Causation is actually rooted in pagan religious thought that knows nothing of the reality of the grace of God! It is because the pagan world is under such naturalistic thinking that Christians need to take the Gospel of grace to the ends of the earth.
