“You should be often exhorting and counseling and warning others, especially at such a day as this: ‘Let us hold fast the confession of our hope without wavering, for he who promised is faithful. And let us consider how to stir up one another to love and good works, not neglecting to meet together, as is the habit of some, but encouraging one another, and all the more as you see the Day drawing near’ (Heb 10.23-25; see also 2.12-14).
When you counsel and warn others, do it earnestly, affectionately, and thoroughly. And when you are speaking to your equals, let your warnings be intermixed with expressions of your sense of your own unworthiness and of the sovereign grace that makes you differ. And, if you can with a good conscience, say how you in yourself are more unworthy than they.”
Adapted from Jonathan Edwards’ Advice to Young Converts.
