“But continue thou in the things which thou hast learned and hast been assured of, knowing of whom thou hast learned them;”  
2 Timothy 3:14

The word of God said:
“Those things, which ye have both learned, and received, and heard, and seen in me, do: and the God of peace shall be with you.”  Philippians 4:9
Then he said:
“And the things that thou hast heard of me among many witnesses, the same commit thou to faithful men, who shall be able to teach others also.”  2 Timothy 2:2
Do what you have learnt, teach what you have learnt; just like every Christian should do the word:
“But be ye doers of the word, and not hearers only, deceiving your own selves.”  James 1:22
Every Christian should teach the word:
“Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:”  Matthew 28:19
Every Christian should participate in and communicate effectively the divine verities we have received as new creatures, but the order has to be like Jesus’- you do the word THEN you teach the word.
“…Concerning Jesus of Nazareth, which was a prophet mighty in deed and word before God and all the people:”  Luke 24:19
“…Jesus began both to do and teach,”  Acts 1:1
Why wait till it’s some serious ailment with no pain killing pill before you do the word, when you can start at any moment, and increase in glory? Do!
