Grace is God's unmerited favor

For sin shall not have dominion over you: for ye are not under the law, but under grace. (Romans 6:14)

Grace is simply God's unmerited favor to us

What is Grace? (Christian theology) the free and unmerited favor or beneficence of God; "God's grace is manifested in the salvation of sinners"; "there but for the grace of God go I"  So while we were yet his enemies, he sent his only begotten son down from glory to die for sinners like you and I. So that we would not have to pay a price that we could not bare and his love for us was so great that he could not bare to lose us. So by grace he redeemed us.

Grace is God working in us the will and the desire to do the things that are right and perfect in his site.

Grace is receiving from God what we do not deserve, freely.

Unmerited favor meaning we did nothing to earn it nor could we. Otherwise Mose's could have paid the debt or David but they could not only Christ was able to do that.

Now tell me is there anyone pray tell in your life that could use a little grace from you?  Maybe your spouse?  Maybe its your children? Maybe a co-workers? Maybe its your neighbor?  If God could will it to you as part of your inheritance surely you can spare some for another?
