We must go to church. Sure we can serve God at home. We should serve God all day. Scripture is crystal clear on the need to gather together. No need for opinions and assumptions!
Heb 10:25 not giving up meeting together, as some are in the habit of doing, but encouraging one another--and all the more as you see the Day approaching.
This is the most commonly quoted verse. Paul could not be clearer! We are in the last days, if ever there was a need to gather together it is today. We don't just gather for ourselves but for others. You are part of a family and they need you as much as you need them. We wash each other when we gather together.
Eph 4:11-12 And He gave some as apostles, and some as prophets, and some as evangelists, and some as pastors and teachers, 12 for the equipping of the saints for the work of service, to the building up of the body of Christ;
We can't receive the five fold ministry at... home, alone. How are those given the gift of pastoring from God supposed to exercise it if we are all at home?
1 Pet 5:2 shepherd the flock of God among you, exercising oversight not under compulsion, but voluntarily, according to the will of God; and not for sordid gain, but with eagerness.
Clearly God wanted us all to be in a flock or he would not have stressed the importance of qualified elders shepherding their flocks properly.
James 5:14 Is anyone among you sick? Then he must call for the elders of the church and they are to pray over him, anointing him with oil in the name of the Lord.
Qualified elders are to pray for the sick. Not some one month old Christian who watches televangelism.
Titus 1:9 holding fast the faithful word which is in accordance with the teaching, so that he will be able both to exhort in sound doctrine and to refute those who contradict.
Elders are to expose and remove false teaching. If you are a qualified elder, you can stay at home longer then others. But if you are not, you may never know that you are being deceived.
Titus 1:6 namely, if any man is above reproach, the husband of one wife, having children who believe, not accused of dissipation or rebellion.
How many of us who stay at home / have home meetings meet the qualifications of an elder according to scripture?
1 Cor 11:20-34 That is why many among you are weak and sick, and a number of you have fallen asleep
We must gather together for communion. The repercussion of not having this, is we fail at examining ourselves 1 Cor 11:28-30.
1 Cor 14:26 How is it then, brethren? When ye come together every one of you hath a psalm, hath a doctrine, hath a tongue, hath a revelation, hath an interpretation. Let all things be done for edification.
When we gather, we are each given something by the Lord for the edification of one another. This cannot happen at home alone.
Matt 18:20 For where two or three gather in my name, there am I with them.
This for me is perhaps the most important reason to gather. The presence of Jesus is at church!
