This sermon by Sinclair Ferguson encouraged me greatly regarding the words that I speak. Maybe you’ll enjoy it, too. You can find it here: The Tongue, the Bridle, and the Blessing: An Exposition of James 3: 1 – 12.
The ability, by God’s grace,
to say the right thing,
to the right person,
at the right time,
in the power of the Holy Spirit,
in faith,
is a magnificent grace in the life of the believer.
