Words are delicate and so must be chosen carefully. Let your praises be loud but let your anger and disapprovals be communicated firmly but gently and calmly.
“Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.” – Ephesians 4: 29
“Let your speech be always with grace, seasoned with salt, that ye may know how ye ought to answer every man.” – Colossians 4: 6
“And let us consider one another to provoke unto love and to good works.” – Hebrews 10 24
