We are justified by His grace (Romans 3:24) If we could do anything to merit God's grace, then grace would no longer be grace--it would be works which cannot save us. However, because of His grace, we want to do good works to show our love and appreciation to God for His continual grace extended to us. It's not a set of rules we have to follow, it's Christ's love that overflows from our hearts that prompts us to extend that same grace to others.
By God's grace we are also bestowed with a gift from God uniquely given to us for His purpose to build up and edify others.
I Peter 4, Peter reminds us of the ways we can offer our gifts to show that we love God and His people.
"Above all, love each other deeply, because love covers over a multitude of sins. Offer hospitality to one another without grumbling. Each one should use whatever gift he has received to serve others, faithfully administering God's grace in its various forms. If anyone speaks, he should do it as one speaking the very words of God. If anyone serves, he should do it with the strength God provides, so that in all things God may be praised through Jesus Christ. To him be the glory and power forever and ever. Amen." (I Peter 4:8-11)
The phrase "faithfully administering God's grace in its varioius forms" speaks of grace being in different forms. God provides illuminating grace for every seeker, justifying grace for all believers, strengthening grace for the weak, growing grace for the young Christian, comforting grace for the bereaved, living grace for our daily walk, and dying grace for the end of our journey. No matter what we face today, or tomorrow, the grace of God will perfectly conform to each specially shaped sorrow and trial. There's a plaque that says: "God will never lead you where the grace of God cannot keep you."
We are to grow in grace and in the knowledge of our Lord. I believe we can only grow in our grace bestowed to others when we ourselves have grown to realize what a great gift of grace that was given to us individually through Christ. God's grace prompted God's gift given to us of His Only Son, our Saviour, the Lord Jesus Christ, through faith. Can we do any less than thank God for His grace and for His unspeakable gift, and in turn, be gracious to others!
"Grace to all who love our Lord Jesus Christ with an undying love!" (Eph. 6:24)
