Matt 5:16 (niv) Let your light shine before men, that they may see your good deeds and praise your Father in heaven.”
How do we shine our light?
By using the gifts, talents and abilities that God has given us to help others (Matt 7:12, 1 Peter 2:12, 3:9, Phil 2:14-15, Pro 4:18, Jude 1:23).
Not thinking more highly of yourself would be a start since you would then be able to think of the needs of others before your own (Luke 11:41, Rom 12:3, 2 Cor 9:11).
Gentle speech could also shine (Eph 4:29, 5:4).
God bless you today
