Sing to the Lord, praise His name; proclaim His salvation day after day. Declare His glory among the nations, His marvelous deeds among all peoples. (Psalm 96.2, 3)
The heart and soul of the Christian gospel is a Person, not a church or a particular theology. To evangelize is to make known the good news of Jesus Christ - who He is and what He did! Jesus Christ came to this fallen world, died a sinless death, and was raised from the grave according to the Scriptures. And, as Lord of the heaven and earth, He now provides forgiveness of sins and the indwelling gift of His Holy Spirit to all who repent and believe.
Today, however, many false teachers claim that God speaks equally through all religions and ideologies. Several years ago, I was invited to our local High School to defend the uniqueness of Christianity in a religiously pluralistic society. There was another pastor who presented a view that compromised the Gospel. He maintained that there are many ways to god. You know the line. I asked the class to slowly read John 14.6 and tell me what it says with reference to coming to the Father. Unanimously, they saw that the text was clear; Jesus was the only way. The point is, those who believe that there are many ways to God neither believe the Scripture nor consider a personal faith in the Person and work of Christ to be essential. They maintain that Jesus merely represents one way to god. Christians must reject such speculation as heretical! There is no other way to the Father but through Jesus Christ (John 14.6).
