. . . before or since.
Nobody spoke as boldly, or as authoritatively. "The Father, in fact, judges no one but has given all judgment to the Son, so that all people will honor the Son just as they honor the Father. Anyone who does not honor the Son does not honor the Father who sent Him." (John 5:22-23).
No historical figure other than Christ ever claimed to be "the light of the world." (John 8:12). And, only Christ spoke of himself as the sufficient redeemer. "If you continue in My word . . . you will know the truth, and the truth will set you free." (John 8:31). Most importantly, Jesus Christ is the only person who ever spoke of himself as the God-man. "Have courage! It is I [AM]." (Mark 6:50). The singular, exclusive path to eternal communion with God. "I am the way, the truth, and the life. No one comes to the Father except through Me." (John 14:16). John 14:16 does not leave a lot of wiggle room for liberal neo-orthodoxy which holds all people receive eternal life, or that it is sufficient if you are a "good" person.
Not even in the Quran is Islam's prophet Mohammed given the divine status of a God-man. In the Quran, it is Jesus, not Mohammed who has the ability to raise the dead, and it is in the Quran that Christ was born of a virgin. In the Quran, Mohammed never claimed to be anything other than a man, and never claimed to be able to redeem anyone, not even himself.
Buddha never spoke of himself as God, as a matter of fact, Buddha did not even believe in a Creator God. In the strict sense, Buddha was an atheist.
And Jesus Christ spoke prophetically of his mission on Earth. "I am the good shepherd. The good shepherd lays down his life for the sheep." (John 10:16). In the temple when asked by the powerbrokers for a sign of his authority from Heaven, Jesus spoke in a way that did not become clear until after his death. "Destroy this sanctuary, and I will raise it up in three days." Therefore the Jews said, "This sanctuary took 46 years to build, and will You raise it up in three days?" (John 2:19-20).
And Jesus spoke with a message of warning that flies in the face of post-modern culture and an attitude of inconsequential choice and action. “Enter through the narrow gate, for wide is the gate and broad is the road that leads to destruction, and many enter through it. But small is the gate and narrow the road that leads to life and only a few find it." (Matthew 7:14).
Jesus Christ is the most unique figure in our Earth's history. Nobody has had his influence that is right now growing and getting stronger. Accept Him or reject Him, nobody can ignore him.
