This question may seem silly or juvenile but I assure you I am serious. I would like to join a church I think it would benefit my life. Since I have never been I am not sure of the 'rules'. I haven't exactly lead a Christian life until now but I want to. I didn't know if you could join if you have worked in the 'adult' industry or been a drug user before things like that. Can anyone join?
In case there is any confusion from what has been said, there is a difference between simply attending a church and joining a church. If you desire to know Christ and his love and forgiveness, or even just wish to know more, then there should be no issue in attending any church or trying out various churches.
But I'm quite certain that to "join" a church, by which it is usually meant that one wants to become an actual member, one must be a Christian. In the meantime, we're here to help with questions and learning or simply for fellowship.
If we had to be perfect or leading a Christian life before ever going to church, churches wouldn't exist. Jesus said he came to call the sinners and not the righteous, that it is the sick who need a doctor, not those who are well:
Mat 9:9 As Jesus passed on from there, he saw a man called Matthew sitting at the tax booth, and he said to him, "Follow me." And he rose and followed him.
Mat 9:10 And as Jesus reclined at table in the house, behold, many tax collectors and sinners came and were reclining with Jesus and his disciples.
Mat 9:11 And when the Pharisees saw this, they said to his disciples, "Why does your teacher eat with tax collectors and sinners?"
Mat 9:12 But when he heard it, he said, "Those who are well have no need of a physician, but those who are sick.
Mat 9:13 Go and learn what this means, 'I desire mercy, and not sacrifice.' For I came not to call the righteous, but sinners." (ESV)
