According to the inerrant Word of God, Christianity is the only way to achieve eternal life by accepting Jesus Christ as personal savior. Jesus Christ taught that He is the only way into heaven, that no one can enter heaven unless he or she has received and has accepted by faith His blood atoning sacrifice.
He made it clear that no other faith or person can redeem our eternal souls. Jesus Christ is the only mediator who can span the sin-rift that exists between God and man: “I am the way, the truth, and the life: no man cometh unto the Father, but by me”John 14:6). The only alternative to heaven is an eternity without God in hell and then ultimately in the lake of fire with Satan and his demonic hordes.
