It's a fair question. As a Christian I cannot count the number of times I've told people, "I'm a Christian", or "I'm a follower of Jesus", or "I'm a believer", or however I packaged the fact that I personally knew and loved God - only to have an INITIAL response of a look that said, "I don't need those rules in my life."
"No, but you do need that LIFE in your life."
But honestly, is that really what Christians are known for - their rules? Their boring lives? Or their morality?
Listen, I believe that rules of living that come from God's word (the Bible) are good to have. I do not think living a bored life is a good idea. And I think morality is a good thing.
But as a Christian I would rather be known for my power than for my rules.
Sidenote: some might call having rules in your life "legalism", but it's only legalism if I put my non-scriptural standard of living on you. If I superimpose my way of life on you, than that can definitely be legalistic, as I understand it to be now. BUT if I preach God's word to you under the inspiration of the Holy Spirit - that is not legalism - it's truth! Accept it, reject it, mull it over or put it on the shelf... up to you. And its up to me when I hear truth. But there is a difference between preaching legalism and preaching truth.
Back to the point though... I would rather be known be known for my power as a believer in Jesus than for the strict way that I live my life. Reason being is that I want to help someone know Jesus. As far as I can tell from scripture - there is only one way to be a witness for Jesus - and that is to demonstrate the POWER of God to actual people. Obviously that power is from the Holy Spirit as highlighted in the below scripture which preceded the birthing of the church in Acts chapter 2 - Jesus speaking:
8 But you will receive power when the Holy Spirit has come upon you, and you will be my witnesses in Jerusalem and in all Judea and Samaria, and to the end of the earth.” (Acts 1:8)
Seems pretty clear to me.
ps. I love theology and think it's necessary - I just think theology should lead to a powerful life for God!
pps. I know love for God, each other, other people etc. is the way to show we belong to God. But love and power in the life Jesus and the apostles always went hand in hand. More love = more power.
