 Remind them to be submissive to rulers and authorities, to be obedient, to be ready for every good work,  to speak evil of no one, to avoid quarreling, to be gentle, and to show perfect courtesy toward all people.  For we ourselves were once foolish, disobedient, led astray, slaves to various passions and pleasures, passing our days in malice and envy, hated by others and hating one another.  But when the goodness and loving kindness of God our Savior appeared,  he saved us, not because of works done by us in righteousness, but according to his own mercy, by the washing of regeneration and renewal of the Holy Spirit,  whom he poured out on us richly through Jesus Christ our Savior,  so that being justified by his grace we might become heirs according to the hope of eternal life.  The saying is trustworthy, and I want you to insist on these things, so that those who have believed in God may be careful to devote themselves to good works. These things are excellent and profitable for people.
Titus 3:1–8 ESV
Remember our main approach through this whole series:
Whenever we talk about Jesus, we can be as humble in our conversation as Christ was when He talked to people. This passage talks about being kind, gentle, avoid quarreling.
At one time, we too were foolish! Enslaved and living in malice, but the kindness of Jesus showed up and changed us!
God’s people should never be arrogant or condescending when they talk to others because at one time we were just like (or had the full capabilities to be like) every person we talk to.
