Church
Maybe you were going to the wrong church? The Bible promotes meeting together with fellow believers, to worship together and strengthen faith.
Matthew 18:20
"For where two or three have gathered together in My name, I am there in their midst."
Hebrews 10:24,25
and 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.
Also, consider evangelism. The churches are behind most missionaries, and think of how many people have given their hearts to Jesus after going to church.
Matthew 28:18-20
And Jesus came up and spoke to them, saying, "All authority has been given to Me in heaven and on earth. Go therefore and make disciples of all the nations, baptizing them in the name of the Father and the Son and the Holy Spirit, teaching them to observe all that I commanded you; and lo, I am with you always, even to the end of the age."
Early Christians, the ones who had the Truth before it was distorted, found importance in meeting regularly at the synagogues. Jesus taught in the synagogues on countless Sabbaths, and His disciples continued this practice long after He was risen, ministering and bringing thousands to salvation. Those that became saved didn't stop going but continued to attend to further their relationship with Jesus.
1 Timothy 4:13,16 (Paul speaking)
Until I come, give attention to the public reading of Scripture, to exhortation and teaching.
Pay close attention to yourself and to your teaching; persevere in these things, for as you do this you will ensure salvation both for yourself and for those who hear you.
There is no doubt that only a small portion of church-goers today have real faith, but I don't think we should throw out the baby with the bathwater.
