I wonder if it should be the other way around. What if we talked the walk instead? Would we do a lot less talking because we don't want to expose our failures? Would we come off as less hypocrytical? Would that inspire us to increase our character in order to have grounds to say more? Would there be a lot less talking and more doing?
Proverbs 17:28 - Even a fool who keeps silent is considered wise; when he closes his lips, he is deemed intelligent.
Proverbs 19:1 - Better is a poor person who walks in his integrity than one who is crooked in speech and is a fool.
