(2 Timothy 2:24-26)  And the Lord’s servant must (1)not be quarrelsome but kind to everyone, (2)able to teach, (3)patiently enduring evil, (4)correcting his opponents with gentleness. God may perhaps grant them repentance leading to a knowledge of the truth, and they may come to their senses and escape from the snare of the devil, after being captured by him to do his will.

Able to teach

Not only should a Servant study the word, they should be able to lead others to the truths revealed to them by God. The Lord places truths in the hearts of servants who seek Him in order to serve His specific purpose. (Isaiah 55:11) so shall my word be that goes out from my mouth; it shall not return to me empty, but it shall accomplish that which I purpose, and shall succeed in the thing for which I sent it. Those truths can be told and shown to others through the action of His servant in order to spread His love to the people He has put into their lives. The word of God is not something we are meant to keep to ourselves, but to share with a lost world.
