We bring heartache upon ourselves by what we say and how we say it. “Put a muzzle on my mouth, LORD!”
Proverbs 13:6 Righteousness guards the man of integrity, but wickedness overthrows the sinner.
Let’s look at this verse in light of verses 2 and 3:
 From the fruit of his lips a man enjoys good things, but the unfaithful have a craving for violence [a subduing, ruling over the other person].
 He who guards his lips guards his life, but he who speaks rashly will come to ruin.
Our natural tendency is to operate without the participation of the Holy Spirit. We must put on what I call “filters” through which to view our circumstances, see God and ourselves, and to know how to treat others. These filters are the Scriptures:
Philippians 2:3-5 Do nothing out of selfish ambition or vain conceit, but in humility consider others better than [before] yourselves.  Each of you should look not only to your own interests, but also to the interests of others.  Your attitude should be the same as that of Christ Jesus: Humility!
There is another set of filters that deals specifically with how we treat others:
Ephesians 4:1-3 As a prisoner for the Lord, then, I urge you to live a life worthy of the calling you have received.  Be completely humble and gentle; be patient, bearing with one another in love.  Make every effort to keep the unity of the Spirit through the bond of peace.
This unity of the Spirit is key; it is kept through the bond of peace. This bond can only be obtained and maintained by grace:
Ephesians 4:7 But to each one of us grace has been given as Christ apportioned it.
Let’s ask for the filter of grace today. May we become known as His gracious people.
