Romans 1:11-13
11 I long to see you so that I may impart to you some spiritual gift to make you strong— 12 that is, that you and I may be mutually encouraged by each other’s faith. 13 I do not want you to be unaware, brothers and sisters, that I planned many times to come to you (but have been prevented from doing so until now) in order that I might have a harvest among you, just as I have had among the other Gentiles.
1 Thessalonians 5:11-24
11 Therefore encourage one another and build each other up, just as in fact you are doing.
12 Now we ask you, brothers and sisters, to acknowledge those who work hard among you, who care for you in the Lord and who admonish you. 13 Hold them in the highest regard in love because of their work. Live in peace with each other. 14 And we urge you, brothers and sisters, warn those who are idle and disruptive, encourage the disheartened, help the weak, be patient with everyone. 15 Make sure that nobody pays back wrong for wrong, but always strive to do what is good for each other and for everyone else.
16 Rejoice always, 17 pray continually,18 give thanks in all circumstances; for this is God’s will for you in Christ Jesus.
19 Do not quench the Spirit. 20 Do not treat prophecies with contempt 21 but test them all; hold on to what is good, 22 reject every kind of evil.
23 May God himself, the God of peace,sanctify you through and through. May your whole spirit, soul and body be kept blameless at the coming of our Lord Jesus Christ. 24 The one who calls you is faithful, and he will do it.
Any teacher who is building up, encouraging, and exhorting the Body about who they are in Christ while also preaching the Gospel is doing exactly what they need to be doing.
One more:
Ephesians 4:11-16
11 And he gave the apostles, the prophets, the evangelists, the shepherds and teachers, 12 to equip the saints for the work of ministry, for building up the body of Christ, 13 until we all attain to the unity of the faith and of the knowledge of the Son of God, to mature manhood, to the measure of the stature of the fullness of Christ, 14 so that we may no longer be children, tossed to and fro by the waves and carried about by every wind of doctrine, by human cunning, by craftiness in deceitful schemes.
15 Rather,speaking the truth in love, we are to grow up in every way into him who is the head, into Christ, 16 from whom the whole body, joined and held together by every joint with which it is equipped, when each part is working properly, makes the body grow so that it builds itself up in love.
