Is it really necessary to be at church? Well I will let God tell you in two simple verses:
1 John 1:7 (NKJV)
"But if we walk in the light as He is in the light, we have fellowship with one another, and the blood of Jesus Christ His Son cleanses us from all sin."
What does this mean? If we are living in God's will, we DO have fellowship with other believers. The flip side is that if you are not living right (in true faith in Jesus Christ), you will fade out of church all together if you are not careful. In fact, the Bible says that we isolate ourselves when we get into, "me, myself, and I" mode:
Proverbs 18:1 (NKJV)
"A man who isolates himself seeks his own desire; he rages against all wise judgment."
Luke 21:34 (NKJV)
“But take heed to yourselves, lest your hearts be weighed down with carousing, drunkenness, and cares of this life, and that Day come on you unexpectedly."
We are warned here, by Jesus Himself, of the danger of getting too busy for God, too saturated with this world's cares, and ending up not ready when He returns (being spiritually drunk; Jesus was not referring to alcohol because He specifically refers to our "hearts"/spiritually speaking).
Folks, Jesus is coming back very soon...and church attendance is one of the 3 essential ingredients to your life of faith:
2. Bible reading
If you need Jesus (and we all do), then you need to nurture your spiritual life more than any other part of life...because out of your spiritual life flow all other things. Be faithful to your church...not only for your own well being, but for your babies, and for those who need your gifts (hospitality/preaching/prayers/encouragement) at church.
Beware of excuses, because they are often the "booze talking."
One last passage to admonish you:
Hebrews 10 (NKJV)
"24 And let us consider one another in order to stir up love and good works, 25 not forsaking the assembling of ourselves together, as is the manner of some, but exhorting one another, and so much the more as you see the Day approaching."
What "Day"? The Second Coming of Jesus Christ (which is evidently near)
What is "not forsaking"? Don't skip church
