And God saw the light, that it was good; and God divided the light from the darkness….Then God said, "Let there be a firmament in the midst of the waters, and let it divide the waters from the waters." Thus God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament; and it was so. Genesis 1:4, 6-7
God is in the business of division. As in creation, He divided whatever was necessary in order to bring order. He divides light and darkness today also. That is why His people are in this world but not of it. God’s children are separated from the world as they are sanctified, or set apart, for the things of God. As Christians, we think of the Lord as One who wants to make “everything ok” or to bring peace to a given situation. However, the Lord Jesus clearly said that He came to divide.
Do not think that I came to bring peace on earth. I did not come to bring peace but a sword. For I have come to set a man against his father, a daughter against her mother, and a daughter-in-law against her mother-in-law; and a man's enemies will be those of his own household. He who loves father or mother more than Me is not worthy of Me. And he who loves son or daughter more than Me is not worthy of Me. And he who does not take his cross and follow after Me is not worthy of Me. He who finds his life will lose it, and he who loses his life for My sake will find it. Matthew 10:34-39
If you have troubles with loved ones who don’t know the Lord, be at peace in the Lord. It is the work of the Lord in your life that has changed you so that you feel the division. Your love for your loved ones shouldn’t change, but your heart’s desire to see them come to Christ will set you apart or divide you from them. Keep praying, keep loving and keep your peace in Jesus. He didn’t give peace to the world but brought peace to you individually as He set you apart for Him.
