The Bible was written by particular people, in a particular culture at a particular time, and yet, Christians also believe that it was written by the Holy Spirit of God. Believing both of these things simultaneously requires us to exercise wisdom and discernment when studying and applying the Scriptures. Take Matthew 6:16-18 for example:
“And when you fast, do not look gloomy like the hypocrites, for they disfigure their faces that their fasting may be seen by others. Truly, I say to you, they have received their reward. 17 But when you fast, anoint your head and wash your face, 18 that your fasting may not be seen by others but by your Father who is in secret. And your Father who sees in secret will reward you.” (Matthew 6:16–18 ESV)
There is a clear and obvious point being made in this passage: beware the danger of religious hypocrisy! Do your acts of religious devotion and piety in secret. Do it for the Lord. Do not do it for the approval of others.
Fair enough.
