This verse is really powerful and convicting. How many times we end up in situations when someone starts yelling and loosing their temper easily. Short temper people can really cause a peaceful situation in disturbing and horrific one. I feel there are people who easily give in to the devil's provocation inside their heart and they easily burst in anger and start yelling at other person. Many times a believer's nature is not changed or transformed by renewing of the mind and live and work with other believers and really cause trouble, time to time they will blast and yell or show their attitudes. It is very unhealthy to work in such environment. Our peace gets disturbed and holiness questionable.

If we also read other translation of the above verse it becomes more clearer that we should make all efforts to avoid such situations where we are tested and also others who are weak and carnal.

ESV: Strive for peace with everyone, and for the holiness without which no one will see the Lord.

NIV: Make every effort to live in peace with everyone and to be holy; without holiness no one will see the Lord.

NLT: Work at living in peace with everyone, and work at living a holy life, for those who are not holy will not see the Lord.

Strive, Make every effort, and work to live in peace with everyone.

Living in peace with others is one of the important aspect of walking in holiness, and it is clearly written that without Holiness it is impossible to see the Lord.

Do you want to see the Lord in your life, walk in peace and holiness. 

"Oh Dear God, lead us not into temptation but deliver us from evil.."
