Throughout the Old Testament, we see Israel wandering away from God. The pull of the cultures around them was too great for them. The same thing happened to the Galatians, the Corinthians, the Ephesians, and several of the churches Jesus warned in Revelation. The pull of culture, peer pressure, and the oppression of an ungodly society against believers are real and powerful.
Psalm 11:3 (Amplified Bible) says:
"If the foundations of a godly society are destroyed, what can the righteous do?"
What can we do to make sure we don't fall victim to false beliefs that look and sound good? What can we do to believe like Jesus and live a godly life when we're bombarded by so many conflicting ideas, when we're pressured to go along with the masses?
The principles of the Word of God are the walls of protection that guard us, give us life, and defeat the schemes and destroy the works of the devil.
There are absolute moral truths which are defined by God in the Bible. They don't change over time or in different cultures. They're always true. These truths determine right and wrong, regardless of our circumstances, our feelings, or what we want to do.
Colossians 2:8 says:
"Don’t let anyone capture you with empty philosophies and high-sounding nonsense that come from human thinking and from the spiritual powers of this world rather than from Christ."
