God is glorified when we use our gifts to build up the church. God gave spiritual gifts so that the members of the body of Christ could by them lift up one another, together. Spiritual gifts are designed to edify the church. You are there not only to get but also to give. This responsibility does not just belong to the pastor or a few of the church leaders.
Every member is gifted, and every member is then responsible to edify the body with that gift.
And for the whole body to be fully edified, all the gifts are needed. The body is maimed and hurting without all the members functioning as they should. Again this was precisely the problem at Corinth. Everyone was out for number one. Gifts were desired to edify self, or even to display self.
