Jesus purposely left no wiggle room when it came to the topic of salvation, explaining that the pathway is exclusive, and that path is through Him.
In Matthew 7:13-14 and Luke 13:23-24 we see Jesus saying that "narrow is the gate" and "narrow is the way." So without question Jesus is saying that Christian way is not one that most will follow. In fact, He says that only "a few will find it."
A lot of people speculate about the number of people who will embrace Jesus as the way, but that's not the point God wants us to take away from that scripture. We know from John 3:16 that God's desire is for none to perish but for all to have eternal life. God's desire is clear, His desire is for everyone to be saved.
Let's take an overhead view of the entire third chapter of John. We start with the story of Nicodemus, a Pharisee and member of the Jewish ruling class, who visited Jesus to discuss how he could be saved.
