It is full-time position
A "non-serving Christian" is a contradiction in terms
You were chosen to tell about the excellent qualities of God - 1 Peter 2:9
You are commanded to serve God
For Christians, service is not an option
Spiritual maturity is never an end in itself
Maturity is for service, we grow up in order to give out
Impression with expression cause depression
Study without service leas to spiritual stagnation
Galilee lake full of life - takes in water but also gives out
Dead sea - takes in but the is no outflow
Not who is going to meet my needs -> Whose needs should I meet?
