Romans 12:7

if service, in our serving; the one who teaches, in his teaching;

if it is serving, then serve; if it is teaching, then teach;

if service, use it in service; if teaching, in teaching;

If your gift is serving others, serve them well. If you are a teacher, teach well.

if it is service, by service; if it is one who teaches, by teaching;

Or ministry, let us wait on our ministering: or he that teacheth, on teaching;
