For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Ephesians 2:8"
The grace of God is the favor and ability of God that is given to the children of God to live a fulfilling Christian life, but you only receive grace through an act of faith by accepting Jesus Christ as your Lord and personal Savior.
This does not demand any work on the part of the recipient because all the work for grace was already done by Jesus Christ on the cross of Calvary.
When you receive grace, use it to better your family, job, education, aspirations, marriage, singleness, etc. Since it is a gift received by an act of faith, use it through faith by confessing it over your life.
Then go ahead and do the work committed to you, and you will certainly succeed. Hallelujah!
