Shalom: Peace of G-D, To Walk in Faith

To walk in Shalom is to walk in Faith. Shalom and Faith both can only come from G-D our Father. Seek first the Kingdom of G-D, and His Righteousness and all these things will be added unto you. Matt 6:33

Shalom is a state of blessing, peace, wholeness, completeness, one of being safe, state of prosperity, restfulness => being blessed is the state of being Happy and content in, through, and with G-D our Father. 

When you say "Shalom" to an individual you are extending a blessing, peace, wholeness towards them that can only be extended through the power of the Holy Spirit (the same Spirit of G-D that moved across the face of the waters when G-D spoke the earth into existence).

24 " ' "The LORD bless you 
and keep you;
25 the LORD make his face shine upon you 
and be gracious to you;
26 the LORD turn his face toward you 
and give you Shalom." '

Numbers 6:24-26
