what does the bible say?
Jesus taught about the narrow gate in Matthew 7:13-14 and Luke 13:23-24. In both passages, entrance through the narrow gate is limited to only a small group of people. This has caused concern among some readers, who may wonder how narrow is the narrow gate?
Jesus tells us in John 10:9 that He is the gate (or door) through which all must enter eternal life. Jesus alone is "the way, the truth, and the life" (John 14:6). The deciding factor is whether a person will believe in Jesus, entering through Him as the gate.
By narrow, Jesus means exclusive. He claimed to be the only way to know God (John 14:6). Most people, even in Christianity, find it difficult to believe that God's indescribable gift of eternal life is absolutely free and that the only way to obtain it is to take Jesus at His word (John 11:25-26).
