“If you endure chastening, God deals with you as with sons; for what son is there whom a father does not chasten? But if you are without chastening, of which all have become partakers, then you are illegitimate and not sons. Further, we have had human fathers who corrected us, and we paid them respect. Shall we not much more readily be in subjection to the Father of spirits and live? For they indeed for a few days chastened us as seemed best to them, but He for our profit, that we may be partakers of His holiness.” Hebrews 12:7-10.
“For whom He [God] foreknew, He also predestined to be conformed to the image of His Son [Jesus Christ], that He might be the firstborn among many brethren.” Romans 8:29.
Matthew 15 may be divided into three different segments, which, on the surface seem unrelated. This apparent lack of relationship causes us to miss a great deal.
“Another parable He put forth to them, saying: ‘The kingdom of heaven is like a man who sowed good seed in his field; but while men slept, his enemy came and sowed tares among the wheat and went his way. But when the grain had sprouted and produced a crop, then the tares also appeared. So the servants of the owner came and said to him, “Sir, did you not sow good seed in your field? How then does it have tares?” He said to them, “An enemy has done this.” The servants said to him, “Do you want us then to go and gather them up?” But he said, “No, lest while you gather up the tares you also uproot the wheat with them. Let both grow together until the harvest, and at the time of harvest I will say to the reapers, ‘First gather together the tares and bind them in bundles to burn them, but gather the wheat into my barn.’”’” Matthew 13:24-30.
