Jesus declared the foundation of the Christian church in Matthew 16:18, "I say also unto thee, that thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it." This verse shows us that the foundation of the church was based on Peters profession of faith in response to Jesus raising the question, "Who do you say that I am?" Peter answered, "You are the Christ, the Son of the living God." Matthew 16:16.
After over 2000 years the road map to accepting Christ has not changed. First, we believe that Christ is, and the He is all that He claims to be. Second, were are convicted of our sins and recognize we are in need of a Savior. We then confess Him before man after which Jesus promises to confess us before the angels and God. Finally, we are baptized and resurrected to walk in a new life of Christian living.
Accepting Christ is not the end of the faith journey, but the beginning. We are called to faithfulness In His church. Some People treat accepting Christ and joining the church like fire insurance. Sort of like, I need to do this to purchase my ticket to heaven and then I can return to my old preoccupations. Paul addressed this attitude in the book of Romans 6:1-4, "What shall we say then? Shall we continue in sin, that grace may abound? God forbid. How shall we, that are dead to sin, live any longer therein? Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death? Therefore, we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life."
The Apostle Paul stressed the importance of continued faithfulness in his writings to the Corinthian church when he wrote in I Corinthians 4:1-2, "Let a man so account of us, as of the ministers of Christ, and stewards of the mysteries of God. Moreover, it is required in stewards, that a man be found faithful."
Christ has laid the foundation for the church and every generation and individual Christian needs to be careful how he or she builds upon it.
