Serve with fervent zeal

Matt 5:16

Your light will shine before men, becausr you live amongst them and the shining of your light is equated to good works.

This doesn't mean they'll to praise you,but praise God because eventually they will see the link between you and thr Lord God. Because they'll see that your light is so special it can only come from Heaven above.

Your good works could be your seal for the Lord.
Titus 2:14
Pslam 69:9
1 Pet 1:22
James 5:16

If you're going to serve the Lord serve him with fervent zeal. These go together and be consistent with it. Let your heart be plain and open. Don't put on a facade as you cannot maintain it for long as the truth will out.

Ephe 6:24
Phil 1:10

Sincerity equals truthfulness. Always speak the wall even when your back is against the wall. This needs courage and you can get that from the Lord.

Matt 25:21

Loving the Lord is first and foremost, then love your neighbour as yourself. You cannot love your neighbour nor yourself if you do not love the Lord first!
