If you see members going through the motions without the passion and dedication that animated the first century Christians, it's a sure sign that they are just "copying" others' expressions of Biblical values rather than actually holding those values themselves. To remedy this, we must encourage them to understand the values and then set them free to go and live those values the way they see fit. In other words - if it's just an opinion, keep it to yourself unless it's simply a friendly discussion. Forcing opinions on others is one of the quickest ways to push people out of the church. Just because something matters a lot to you, and because you think it's super important, does not oblige others to agree. If it's not in the Bible, it isn't a requirement - period.
Consider Christ's teachings:
Then Jesus said to the crowds and to his disciples, “The scribes and the Pharisees sit on Moses' seat, so do and observe whatever they tell you, but not the works they do. For they preach, but do not practice. They tie up heavy burdens, hard to bear, and lay them on people's shoulders, but they themselves are not willing to move them with their finger... “But woe to you, scribes and Pharisees, hypocrites! For you shut the kingdom of heaven in people's faces. For you neither enter yourselves nor allow those who would enter to go in. Woe to you, scribes and Pharisees, hypocrites! For you travel across sea and land to make a single proselyte, and when he becomes a proselyte, you make him twice as much a child of hell as yourselves. Matthew 23:1-4,13,15
If this post offends you or causes you to feel uncomfortable, then let me be very clear. I am talking to you. I challenge you and hope that you will consider and reflect on these things so that you soften your heart and let God start working through you again.
