Salvation is a claim about God. God’s selfassigned task is “working salvation in the earth” (Ps 74:12). God is addressed as “God of our salvation” (Ps 65:5). For some, salvation is rescue, deliverance, and victory. For others, it is healing, wholeness, completion, and rest. Isaiah speaks of salvation as a great economic reversal in which God gives a free banquet for the poor (Isaiah 55). Whatever salvation means, its meaning must be too rich for any single definition.
In Scripture, salvation is what God does.
— William H. Willimon, Who Will Be Saved?
I love the of combination of an understanding of salvation as too rich for any single definition counterbalanced with the succinct summary of salvation as what God does.
