Being Christ to those around us is a 24/7 calling. We must allow Him to live through us all the time, especially concerning what we say.
Proverbs 20:3 It is to a man’s honor to avoid strife, but every fool is quick to quarrel.
I wish there were a five-second governor on our mouths. There would be so much that would go unsaid because the Holy Spirit would have time to put a muzzle on our mouths (Ps. 39:1)!
Colossians 4:6 Let your conversation be always full of grace, seasoned with salt, so that you may know how to answer everyone.
The grace comes from considering others better than ourselves (Phil. 2:3) and being His ambassadors (2 Cor. 5:20); the salt comes from the Gospel, the Good News of Jesus Christ, which entails salvation, sanctification, and glorification.
Salvation-we are to reconcile people to God through Christ.
2 Corinthians 5:20 We are therefore Christ’s ambassadors, as though God were making his appeal through us. We implore you on Christ’s behalf: Be reconciled to God.
Sanctification-we are growing to be like Him in every way.
1 John 4:17 In this way, love is made complete among us so that we will have confidence on the day of judgment, because in this world we are like him.
Glorification-One day, we will receive glorified bodies, ones that have no sin nature and are perfect in every way–just like Jesus!
1 Corinthians 15:51-54 Listen, I tell you a mystery: We will not all sleep, but we will all be changed—  in a flash, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, the dead will be raised imperishable, and we will be changed.  For the perishable must clothe itself with the imperishable, and the mortal with immortality.  When the perishable has been clothed with the imperishable, and the mortal with immortality, then the saying that is written will come true: “Death has been swallowed up in victory.”
In the meantime, let’s do our best to allow the Spirit to guide our tongues by waiting a couple of seconds before answering or making a comment. Being “sweet and precious” is important:
Ephesians 4:29-32 Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up according to their needs, that it may benefit those who listen.  And do not grieve the Holy Spirit of God, with whom you were sealed for the day of redemption.  Get rid of all bitterness, rage and anger, brawling and slander, along with every form of malice.  Be kind and compassionate to one another, forgiving each other, just as in Christ God forgave you.
Today, let’s “walk in the way of love (Eph. 5:1)” as we speak kindly to one another with respect, submitting to one another out of reverence for Christ (Eph. 5:21).
