14 Colossians 3:12-13

So embrace, as the elect of God, holy and beloved, a spirit of mercy, kindness, humbleness of mind, meekness, and longsuffering.  Bear with one another and forgive one another.  

Sometimes, we have to set our attitude before we leave the house.  If we know that if we have a spirit of kindness towards others, we will be less offended and not in strife, then kindness is the way to go.  If we walk in love and are longsuffering, then peace will be with us wherever we go.  Our prayers getting answered depends on our attitude towards others.  We are in charge of how we react.
