2 Timothy 3:16-17 "All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be complete, equipped for every good work.”
You probably know this text. Many of us, though, read it and teach it without meditating on it. You're privileged to teach and preach the Scripture today — and then just trust that it will accomplish its work. God breathed it, so just teach it.
