The Number Four Reason Why We Need to Be in Church on Sunday Is: Our sanctified Christian Lives need us to be in Church on Sunday. "Therefore, take up the full armor of God, so that you will be able to resist in the evil day, and having done everything, to stand firm." (Ephesians 6:13) The devil wants us to turn against God, lose our faith and our eternal salvation. Our life of sanctification works against this plot. In Church we learn how to live according to God's will and thwart Satan's evil attacks.
The Number Five Reason Why We Need to Be in Church on Sunday Is: Our families need us to be with them in Church on Sunday. "Fathers, do not provoke your children to anger, but bring them up in the discipline and instruction of the Lord." (Ephesians 6:4) "Do as I DO," is an excellent teaching method for children, spouses, and even parents; much more so than merely, "Do as I say."
The Number Six Reason Why We Need to Be in Church on Sunday Is: Our fellow members need to have us with them in Church on Sunday. "Let us consider how to stimulate one another to love and good deeds, not forsaking our own assembling together, as is the habit of some, but encouraging one another; and all the more as you see the day drawing near." (Hebrews 10:24-25) Whether it should be this way or not, the simple truth is that our fellow members often become discouraged and disheartened when far too many seats remain empty in church. We are in this struggle against the devil together, and we need to show our unity especially in our Sunday worship.
