Don't say at all......

 Psalm 19:14

May the words of my mouth and the meditation of my heart be pleasing in your sight, O LORD, my Rock and my Redeemer.

Words do have the power to break or mend, wound or heal. 

Abba Father may our words bring healing to the wounded, 

hope to the hopeless, bind the broken, help to lead the lost and 

wandering souls to you. Let our words be seasoned with salt. 

Forgive us for reckless words, O Lord 

In Jesus Name Amen

Colossians 4:6

Let your conversation be always full of grace, seasoned with salt, so that you may know how to answer everyone.
