The simple answer is, Jesus! Why? Because he alone saves.
When Jesus was comforting his disciples, he explained:
“I am the way and the truth and the life. No one comes to the Father except through me.“
John 14:6
Only Christianity offers absolute assurance of eternal life as it is a gift of God’s grace for all who by faith trust in Jesus as Savior and Lord. (Ephesians 2:8). Christianity is about Jesus, the Cross (forgiveness of sins) and his Resurrection and Ascension, and his second coming.
The founders of all other religions are dead. They have offered some sound platitudes for living a moral life, but no hope for eternity based on solid evidence.They are religions of good works and self sacrifice to gain a pardon for the worshiper’s sins.
