⁶ Let your conversation be always full of grace, seasoned with salt, so that you may know how to answer everyone. (Colossians 4)

This is a great secret for success, success in your relation with your children, success with your spouse, with your co-workers, with your brothers and sisters in Christ. The key word is "always," we must be consistent. 

Please read Colossians 4 - 1 Thessalonians 2.

May the Lord richly bless you!
