God's AMAZING GRACE!!! It is also HIS power to intervene for us, protect us, heal us, restore, bless, etc. HIS power is unlimited, and unfailing.
Your worst days are never so bad that you are beyond the reach of God's grace. And your best days are never so good that you are beyond the need of God's grace. -Jerry Bridges // The Discipline of Grace // http://desiringgod.org/blog/posts/100-quotes-from-you-on-sanctification
When feeling defeated from years of trying and failing... | @LysaTerKeurst
So you see... it's mercy, not grace. You received mercy, not grace. Grace is always from God. Mercy requires that we effect change to continue to receive it.
For it is by grace you have been saved, through faith - and this not from yourselves, it is the gift of God - not by works, so that no one can boast. Ephesians 2:8-9
