What is the gospel? It is the greatest news that we will ever hear in our lifetime.
It is the news that Jesus defeated Satan and has restored the reign and rule of God over all creation and will one day return to complete the restoration and rule forever.
It is the news that though we have rebelled against God and are separated from Him we can be reconciled and restored in our relationship with Him and be a part of His family forever through Jesus.
It is the news that through the sinless life, sacrificial death and bodily resurrection of Jesus sin, death and hell have been defeated.
This is the most amazing news when you consider that we all rejected God and turned away from Him to be our own gods deciding for ourselves what is right and wrong and seeking life, happiness and purpose on our own terms in created things rather than in the Creator whom we were made by and for.
In light of this incredible news what must we do? First we need to recognize our rebellion against God not making excuses for it and confess it to Him. Second we need to turn from our rebellion back to God giving Him His rightful place in our hearts and lives. Third we need to put our trust in Jesus and all that He did to reconcile us and then follow Him the rest of our lives.
