Romans 12:2, Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect.
Colossians 3:17, And whatever you do, in word or deed, do everything in the name of the Lord Jesus, giving thanks to God the Father through him.
Colossians 2:8, See to it that no one takes you captive by philosophy and empty deceit, according to human tradition, according to the elemental spirits of the world, and not according to Christ.
A worldview is a set of ideas, values, and presuppositions. It’s like putting on a pair of sunglasses that color how you view life, people, and ideas. People collect little pieces of their worldview through parents, school, movies, and friends. A Christian worldview is based on the Bible.
This is one of the reasons why white churches of the 18th and 19th centuries did not work to end slavery (while many individual White believers did work to end slavery).
In fact, in the 18th and 19th centuries many believed the Bible affirmed slavery and the inferior status of persons of African descent (which was part of their worldview at that time.)
