In the next-to-last book of the Bible, the apostle Jude exhorts us to "earnestly contend for the faith which was once delivered to the saints" (Jude 3). His warning refers primarily to professing Christians who would dilute the faith instead of defending it.

“The LORD is gracious, and full of compassion; slow to anger, and of great mercy” (Psalm 145:8)

“For if these things be in you, and abound, they make you that ye shall neither be barren nor unfruitful in the knowledge of our Lord Jesus Christ” (II Peter 1:8).

“And the people murmured against Moses, saying, What shall we drink?” (Exodus 15:24).
