One way at looking at this – can be learned by pondering the words from British clergyman Joseph Hall, who said there are three reasons we aren't as thankful as we should be – and those are envy, pride and covetousness.
He said that “envy is looking more at someone else's blessing than our own; pride is looking more at ourselves than our blessings, and covetousness is looking more at what we wish we had than at what we actually have.“
Instead, make up your mind not to put any stumbling block or obstacle in the way of a brother or sister.”
