Shalom

Shalom is the Hebrew word for peace.

But it connotates much more than that. Strong's Concordance says it also means: completeness, wholeness, health, peace, welfare, safety, soundness, tranquility, prosperity, perfectness, fullness, rest, harmony, and the absence of agitation or discord.

Shalom comes from the root verb shalom which means to be complete, perfect and full. The ancient Hebrew people used it as a greeting or a farewell (and as I understand many still do today) and they said in using it you are speaking into someone's life all the good things that it means.

Paul alludes to and expands upon this tradition in his letters using the phrase "Grace and Shalom(Peace)" as a greeting and a farewell.

But more than all that, it stands for the way God intended creation t be. 

The way things were in God's good garden.

In the ancient Jewish mindset God created things in Shalom and once that was broken He set about restoring Shalom.

The great prophet Isaiah told that one day God would send a liberator to Israel to set things right again, and he would be the "prince of Shalom".

God is still in the business of restoring Shalom!
