It is possible to be near the gospel and miss salvation. It is possible to have some knowledge of the gospel and not believe it. It is possible to be close to salivation and not be saved. Proximity does not equal possession.

Beyond making a comparison between Moses and Jesus, Hebrews 3 warns that it is not enough to simply know who Jesus is. Like the people that Moses led, there will be many who miss out on receiving the salvation of Jesus. Those whom Moses led out of Egypt were witnesses to God's great and glorious power but did not have faith and thus did not receive the blessing of the promised land. Likewise, many today have heard the gospel but have not believed in faith and thus have not received the promise of salvation.
