Tips on not hiding your light

In his sermon on “not hiding our lights under a bushel” (Matthew 5:13-16), George MacDonald hands out advice on how to do that in our day-to-day conduct. I found these passages the most relevant:

A Christian who looks gloomy at the mention of death, still more, one who talks of his friends as if he had lost them, turns the bushel of this little-faith love the lamp of the Lord’s light. Death is but our visible horizon, and our look ought always to be focused beyond it. We should never talk as if death were the end of ANYTHING[!]

To let our light shine, we must take care that we have no respect for riches: if we have none, there is no fear of our showing any. To treat the poor man with less attention or cordiality than the rich is to show ourselves the servants of Mammon.
