1 Corinthians 3:1-3
There are many committed followers of Jesus Christ who are focused on pleasing God and growing in faith. But others who identify as Christians don’t concern themselves with spiritual matters at all and instead retain a carnal mindset. This can happen when people start compromising their convictions.
When a believer loosens his grip on God’s Word, he may disobey a command or refuse to believe a certain truth. Or he may simply stop reading Scripture. Sooner or later, something in society will appeal to him, and as he fixates on it, his time and resources are consumed. Slowly this “new love” wins his affection away from the Lord.
After a while, other aspects of the culture that once appeared detestable don’t seem so bad—the believer may dabble and eventually indulge in them with abandon. Inevitably, his witness will be undermined because neither his conduct nor his character is fitting for a man of faith.
It’s important that believers resist giving themselves to things that can never bring lasting peace. If you have yielded to the world’s mindset in some area, repent and return to your first love—the God who saved you. Peace and fulfillment are the reward of those whose sole focus is to please the Lord.
