Hos 10:12 Sow for yourselves righteousness, reap the fruit of unfailing love, and break up your unplowed ground; for it is time to seek the Lord, until he comes and showers righteousness on you.
Whether we are Old or New Covenant believers, we cannot escape this immutable law of sowing and reaping. Paul affirms this law in Gal 6:7-8, "Do not be deceived: God cannot be mocked. A man reaps what he sows. The one who sows to please his sinful nature, from that nature will reap destruction; the one who sows to please the Spirit, from the Spirit will reap eternal life." Basically, we reap what we sow. If we sow seeds of righteousness (righteous deeds, positive words, etc), we will reap the fruit of righteousness. However, if we sow seeds of sin (unethical and immoral acts), we will reap the fruit of destruction. This law is embedded in Creation and we have to obey its imperative.
If we have been sowing seeds of destruction, we end up with a hardened heart. Like the ground that has been left fallow without sowing good seeds for a long season. The top-soil is hardened and the good seed of God's Word bounce off us, even when we hear it. Like the path in the Parable of the Sower, the seed cannot penetrate through the top-soil. The way to get back on the positive cycle of reaping and sowing is to break up the fallow ground of the hardened heart through genuine repentance and seek the Lord. When that happens, the Holy Spirit will rain on us again and we will resume the cycle of righteousness and fruitfulness.
This law of sowing and reaping is often applied to tithing and giving--sow in tithes and reap financial prosperity. However, if we restrict this law only to financial matters, we are spiritually poorer, for this is a generic principle that is applicable to all areas of our life. For example, if we want more love, we sow more love. If we want more friendship we sow more friendship. If we want to be treated more kindly, we treat others more kindly. If we want others to pray for us, pray for others. And so on.
May we examine our heart daily so that it may not be hardened by seeds of unrighteous deeds and words we have spoken but have never confessed nor forsaken in repentance. If we keep our heart soft, the Word of God will be able to work deep within us to transform us by His Spirit.
Father, thank You for the immutable spiritual law You have given us, that we always reap what we sow. May we continue to sow good seeds of love and kindness. Amen.
