Shall Jesus find faith on the Earth?

Luke 18:7 And shall not God avenge his own elect, which cry day and night unto him, though he bear long with them?
Luke 18:8 I tell you that he will avenge them speedily. Nevertheless when the Son of man cometh, shall he find faith on the earth?

Some people sincerely believe that although God avenges His people, and saves them when they cry to Him, that apparently the question about faith on the Earth implies a negative answer.

Is Jesus coming back when there will not be faith on the Earth? The Biblical answer is that there will be faith when Christ returns, because (after all) who is it that He is coming for?

There must be many saved people because the Gospel must go to the nations (see Matthew 24:14; 28:19, 20). There must be many saved because Jesus said one will be taken and one left (which statistically is about 50% of the adult population). Also, the fact the knowledge of God should cover the Earth as the waters cover the sea would make for about 71% of the Earth’s total population (including children), since that is the percentage of water coverage on the Earth’s surface (see Habakkuk 2:14).

The Church, while on Earth, must grow up.

Ephesians 4:13 Till we all come in the unity of the faith, and of the knowledge of the Son of God, unto a perfect man, unto the measure of the stature of the fulness of Christ:

Ephesians 5:26 That he might sanctify and cleanse it with the washing of water by the word,
Ephesians 5:27 That he might present it to himself a glorious church, not having spot, or wrinkle, or any such thing; but that it should be holy and without blemish.
