For from his fullness we have all received grace in place of grace already given. Jn. 1:16 NIV
In place of the grace that God gave through the law of Moses we now are under the grace provided by the blood of Christ. Under the Law the required response was to offer sacrifice. Under grace the required response is surrender. It is human nature for our responses to be actions, to want to do something. But the response God is looking for to grace is that we receive, and allow ourselves to be acted upon.
Lord, thank you for this unearned grace that only Your sacrifice could accomplish.
