“Then shall they deliver you up to be afflicted, and shall kill you: and ye shall be hated of all nations for My name’s sake.  And then shall many be offended, and shall betray one another, and shall hate one another.  And many false prophets shall rise, and shall deceive many.  And because iniquity shall abound, the love of many shall wax cold.
Matthew 24:9-12

Many choose to follow their own path, do their own thing, believe in their own god, and think everybody else ought to do the same thing.  Be tolerant to my own faith, and if you believe different, then we will get along fine; as long as you don’t  mention that there is only one God.

When someone comes along and is bold enough, courageous enough, full of the Spirit of the one true God, and with the love of God in their heart, confronts such a society, and due to lack of true toleration, are filled with hatred for the individual who has been so strong in faith.

Because iniquity shall abound, the love of many shall grow cold.  It is due to the growing of sin, the iniquity of unbelieving, rebellious hearts.

Do not let your heart grow cold in unbelief.  Believe in the Lord Jesus Christ.  Call on His name today.
