2 John 3 (NKJV) Grace, mercy, and peace will be with you from God the Father and from the Lord Jesus Christ, the Son of the Father, in truth and love.
Love, mercy, and grace these three words requires a clearer understanding to realize the importance of what the Apostle John is saying in his greeting. In Ephesians we are told, “But God, who is rich in mercy, because of His great love with which He loved us, even when we were dead in trespasses, made us alive together with Christ (by grace you have been saved)” (Ephesians 2:4-5 NKJV). God is rich in mercy, and because of His great love for us, God saves us by grace. Love is an attribute of God. God is love. But the love of God is not what saves us. Rather the love of God caused God to have mercy and grace on us, in the form of the substitutional sacrifice of His Son Jesus Christ. The love of God had Him create His plan of salvation. The love of God had Him demonstrate mercy towards us by the fulfillment of His plan of salvation. Meaning to say, because God is love, God by His mercy paid the penalty for our sins through the shed blood of His Son Jesus Christ. But we are not saved by love or mercy. Rather we are saved by God’s grace. In Christ alone, by grace alone we are saved. “For by grace you have been saved through faith, and that not of yourselves; it is the gift of God” (Ephesians 2:8 NKJV). You see my friend, “For God so loved the world that He gave His only begotten Son …” (John 3:16 NKJV). God so loved the world that by His mercy He provided a Savior for us, and God can now save us by grace because of what Christ did for us on the Cross. The penalty for sin had to be paid, because God is also just and righteous. God could not wink at our sins, so to speak. The penalty for sin had to be paid. That is why God sent His Son, “to demonstrate at the present time His righteousness, that He might be just and the justifier of the one who has faith in Jesus” (Romans 3:26 NKJV). God saves us by His grace, because God’s mercy provided us a Savior, and it was because God loves us; “… that whoever believes in Him should not perish but have everlasting life.” God is love. God is rich in mercy. And God is full of grace. These truths will never change. This is why John can say, “Grace, mercy, and peace will be with you from God the Father and from the Lord Jesus Christ, the Son of the Father, in truth and love.” Because God is love, God provided us a Savior, and He will never change in truth and love.
God Bless and have a great day in God’s Word.
