A good Christian family is one that lines up with biblical principles and one in which each member understands and fulfills his or her God-given role. The family is not an institution designed by man. It was created by God for the benefit of man, and man has been given stewardship over it.
A strong family unit is one of the very best and most important things in life. The Bible makes this plain in the creation account, where God makes a woman and a man, unites them as "one flesh" and blesses them with the exhortation to "be fruitful and multiply" (Genesis 1:27, 28; 2:23, 24). It revisits the theme in Deuteronomy 11:19 and Proverbs 22:6, where the Lord instructs His people to train up their children in the way of holiness and truth. It underscores the message in the Psalmist's declaration that "children are a heritage from the Lord, the fruit of the womb is a reward" (Psalm 127:3). It emphasizes it in the apostle's solemn warning that "if anyone does not provide for his own, and especially for those of his household, he has denied the faith and is worse than an unbeliever" (1 Timothy 5:8). For all these reasons, we do not hesitate to affirm that there is a strong and inescapable biblical basis for "focusing on the family."
As we know, the Bible says “the life is in the blood” (Lev. 17:11). This is a fact, both biologically and spiritually. The blood in your body is a cleansing agent which purges the toxins and bacteria in our system, and supplies oxygen to vital areas necessary for our survival. Each minute, your heart pumps and circulates blood through miles of inter-connected veins and arteries, passing through the kidneys for filtering, and back into the same circulating cycle. However, in the event that a part of your body were to be severed from the flow of blood, the absence of blood circulation would cause that part to become infected — it would develop gangrene and would die. Survival is not possible without continual circulation of the blood.
So it is within the body of Christ, the Church (1 Cor. 12:27). For the blood of Jesus Christ to have its continual cleansing effect over our sins, we must remain attached to Christ’s body. If we sever fellowship with His body, we risk cutting off the circulation of the cleansing blood!
