Let your light shine before men, so that they may … give glory to your Father in the heavens.—Matt. 5:16.
“When we shine our light before others by living righteously, we are making visible the character of the Father. Some people might claim a contradiction between the instruction here to Let your light shine before men, and in 6:1–6, Be careful not to do your acts of righteousness before men, to be seen by them. However, there is a great difference between the two passages, and it has to do with who is glorified by the good works. In one case attention is drawn to God; in the other, it is drawn to self. It is the Christian’s commission to live in such a way as to make God visible in a world that is blind to him.” – Stuart K. Weber
