I would love to hear your reasons on why you picked what you picked in the comments. Someone asked me this the other day and I thought it was an amazing question to dig down deep and think about what is most important.
Poll: If You Only Could Do One…

This is discipleship for me. Life open and honest, come and follow me, let’s love God and people. Life change happens in relationship and I couldn’t give this up.
Same here man. I’ll lean towards that too. It’s the back bone of our ministry.
I picked small groups because you can take a few people, pour into them, train them the same way to disciple as you do, tell them to do the same and send them out.
Small groups – we all want to be known and this is where that happens. Discipleship within small groups gives space for people to ask questions, share ideas and be a part of something where they participate and not just observe what is going on. The other options are great compliments to small groups, but small groups are key.
Great insight, I agree with you. I would lean more towards this one as well.
I picked the closest to preaching.
Services would be the closest to that one I’m guessing? Why would you do that?
