If you love God, who is that shown in how you live? We should serve God because we are under orders from the ruler of everything. The soul of a person is worth more than the whole universe and we will one day give an account for our actions to God.
We should serve God with gladness and not fear. He equips us, not with cleaver techniques, but with the Holy Spirit; so speak up! However we work, we cannot succeed unless the Spirit is working. In the early Church, the only mute Christian was a dead one!
