2 Timothy 2:24 And the Lord’s servant must not be quarrelsome but must be kind to everyone, able to teach, not resentful.
There are times when we like to be able to prove ourselves better than others by showing them that we know more than them; and yes, we probably all fall into that category – especially as young children!
This verse actually warns about teachers of the word getting caught up in their own vain teachings rather than concentrating on the truth that God gives us to give to others.
As teachers we must always reach out in love and try to communicate as best we can to deliver the Gospel message.
