Colossians 2:6-8

So then, just as you received Christ Jesus as Lord, continue to live your lives in him, rooted and built up in him, strengthened in the faith as you were taught, and overflowing with thankfulness.

See to it that no one takes you captive through hollow and deceptive philosophy, which depends on human tradition and the elemental spiritual forces of this world rather than on Christ.

1 Peter 3:15

15 But in your hearts revere Christ as Lord. Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have. But do this with gentleness and respect, 16 keeping a clear conscience, so that those who speak maliciously against your good behavior in Christ may be ashamed of their slander.

Colossians 4:5-6

Be wise in the way you act toward outsiders; make the most of every opportunity. Let your conversation be always full of grace, seasoned with salt, so that you may know how to answer everyone.

Matthew 9:35-38

35 Jesus went through all the towns and villages, teaching in their synagogues, proclaiming the good news of the kingdom and healing every disease and sickness. 36 When he saw the crowds, he had compassion on them, because they were harassed and helpless, like sheep without a shepherd. 37 Then he said to his disciples, “The harvest is plentiful but the workers are few. 38 Ask the Lord of the harvest, therefore, to send out workers into his harvest field.”
