Matthew 13:24-30 "The kingdom of heaven may be compared to a man who sowed good seed in his field; but while men were sleeping, his enemy came and sowed weeds among the wheat, and went away. So when the plants came up and bore grain, then the weeds appeared also. And the servants of the householder came and said to him, Sir, did you not sow good seed in your field? How then has it weeds?' He said to them, An enemy has done this.' The servants said to him, Then do you want us to go and gather them?' But he said, No; lest in gathering the weeds you root up the wheat along with them. Let both grow together until the harvest; and at harvest time I will tell the reapers, Gather the weeds first and bind them in bundles to be burned, but gather the wheat into my barn.'"
We all change, sometimes we look forward to the changes, sometimes we don't, but God doesn't change, God is the same yesterday, today and forever. Why is this important, there are some people who believe that since God doesn't change, then the things of God shouldn't change either. What do you think? Certainly the Bible doesn't change, there may be new translations, but it still says the same thing. The 10 commandments don't change, they remain the same. The way of salvation has always been by grace through faith in Christ - it hasn't changed. And the church, which is the body of Christ, believers working together, under Christ - that still the same church it has always been. Yet as much as the church remains the same, that is not to say there are not some changes. We no longer sing hymns in German, or read the scriptures using Luther's translation, and we have gone to a new hymnal, with a new order of service - yet we are still Lutherans, worshiping the same God.
The changes in the church are very much like the changes in a seed. What you plant doesn't remain the same, growth involves changes, seeds grow roots, and sprout through the soil, leaves come, and it reaches up to the sky, and in season it bears fruit. Our text has several parables which speak of how the kingdom of God grows, for just as seeds are planted and grow - so the kingdom of God is about planting seeds of faith, and watching them grow. That's why the church appears to change, because we grow in faith.
Faith grows like a seed, it really doesn't have to try to grow, it doesn't need to think what to do next, it just does what it was created to do. So if a seed is wheat in will grow into wheat - and the seed of faith will grow to trust in God more and more - and rely on God more and more - and look to God more and more - until we find that God is at the center of our life.
And if it weren't for sin, that would be the end of the story - the kingdom of God would grow until all people were saved. Sin is like the weeds, God didn't plant them, God doesn't want them to grow - but God doesn't want them pulled out, lest it also pull out tender seeds of faith. Weeds and Wheat grow side my side until the harvest - but at the harvest the outcome is quite different. So what's the difference?
Well, faith grows to eternal life, and the wages of sin is death. If you are dead in you sins and trespasses, you're dead - people don't grow more dead, because death is the end. But faith lives and grows. You may not be able to look into someone else heart, but you can certainly look at your own heart - what do you see?
If you see sins, then now is the time to repent, now is the time to believe the good news that Jesus died for your sins - then when you look to the scriptures, you will see that God has made you a new creation, that the Holy Spirit has worked faith in your heart, and that God will continue to feed that faith with his grace so that you can grow into all he has made you to be.
