There are at least two different kinds of peace. There is the peace that the world offers, and there is the peace Christ offers (“not as the world giveth”). The Hebrew word Shalom implies not only peace for wholeness.
What is the true meaning of shalom?
According to Strong’s Concordance (7965), shalom 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 meaning to be complete, perfect and full.
You will keep him in perfect peace,
Whose mind is stayed on You,
Because he trusts in You. Isa 26:3
If you look up the Hebrew for “perfect peace”, this is the translation for “shalom shalom”.
