When you’re a young christian, it’s almost as if everything is for you. Church feels aimed at you. There’s a special group for people new like you. You get invited to camps and getaways that teach you things you’ve never realised were in the bible. Every other person in church is more mature and wants to help you.
But as you grow in maturity (as you should) you also grow up in the community. You start welcoming new people, you start making the new christian feel at home, you help run the camps, you start leading the groups.
In fact, it’s normal Christian life that there seem to be fewer and fewer people around who are there for you. And more an more people for whom you are there for them.
You can see Paul’s disappointment in the Corinthians… “Brothers, I was not able to speak to you as spiritual people but as people of the flesh, as babies in Christ. I gave you milk to drink, not solid food, because you were not yet ready for it. In fact, you are still not ready, because you are still fleshly.” (1Cor 3-1:3)
Or the writer of Hebrews… “it is hard to make it clear to you because you no longer try to understand. In fact, though by this time you ought to be teachers, you need someone to teach you the elementary truths of God’s word all over again.” (Heb 5:11-12)
Jesus wants us to mature, and maturity means “more like Jesus”; more serving others and less being served. Mature Christians give more than they get.
