Matthew 7:13 Enter ye in at the strait gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many there be which go in thereat:
Matthew 7:14 Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it.
Jesus is not talking about temporal life He is speaking of eternal life.
Few find eternal life. Jesus is the way.
Of the people who claim to believe in Christ many of those don't even know Him and really don't want to know Him.
Matthew 7:22 Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?
Matthew 7:23 And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.

Romans 1:16 For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek.

John 3:36 He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life; but the wrath of God abideth on him.
