Welfare is defined as the state of being well in terms of happiness, peace, prosperity, and general well-being. The complete opposite of welfare would be warfare. In a war there is no peace, but only enmity and a constant lack of peace. Whenever a war ends civilians go out to the streets and celebrate the long awaited peace that has suddenly floods their existence.
Before God redeemed us we were labelled as enemies of God, children of wrath who were gathering up wrath for the day of wrath. But God has taken away that wrath, and He has done so by the only possible means, that is, the very God-Man absorbed that wrath in our behalf. Peace has been declared with God by the atoning death of Jesus Christ. We are no longer called His enemies, but children. No longer is there warfare, now there is welfare and peace. This very peace (Gk; εἰρήνη, eirēnē. Hb; שָׁלוֹם, shalom) is the very foundation of our communion with God.
The Hebrew “shalom” means precisely that, a cessation of enmity and war. Where there was strife there is now serenity and closeness. This is what was accomplished by God’s grace, which is personified in Jesus Christ, the Lord of lords.
