Do it! Paul is giving Timothy some words of wisdon and telling him to do and teach all that Paul has told him. Read 1 Timothy 4:11.
Prescribe and teach these things.
1 TIMOTHY 4:11 NASB
Timothy is not to just keep all this information to himself, he is to teach it. As we learn new things, we are to continue to teach those things to others. We must never allow lessons God has given us to just sit there and not to anything. We are to teach and train others. Does that describe us today?
