The nature of the Christian's work, is a high and hard work, God's goodness requires serious and earnest endeavours. We should aim at glorifying God at all times. Happiness comes through serving and giving God praise. He who has given himself to God may say confidently that the Lord is good and through Jesus nothing but glory is solid and lasting and abides forever.
Each of you should use whatever gift you have received to serve others, as faithful stewards of God's grace in its various forms. 1 Peter 4:10
