While we are to be kind to people, we are not supposed to put more emphasis on pleasing others than pleasing God. We are to glorify God first in all things and we must be diligent on renewing our minds toward knowing God better. When we know Him better, we will care more about pleasing Him than pleasing others. We are called to treat others with love and compassion but also to admonish and guide others, especially believers, toward living lives that glorify God. It is commendable to serve others and be concerned for their interests, but not when it comes at the cost of pleasing the Lord. When we seek to please God, our words and actions have the ability to enrich others and us at the same time because they are empowered by the Spirit.
People-pleasing may sound like a positive trait upfront. It seems admirable to want to be kind to others and make them happy. However, seeking to please other people is different from genuinely seeking their best interest. Also, inherent in the concept of being a people-pleaser is the associated idea that people-pleasers do things based on the amount of favor they think they will get from others. This type of people-pleasing is not actually pleasing other people at all, because it is inherently self-pleasing. People-pleasing becomes unhealthy when pleasing others is more of a motivator than pleasing God. When we're working to please other people in the moment to gain favor to make ourselves feel good, rather than seeking their best, we are not loving others as God loves them. When we're making the reaction of other people our standard for how we evaluate ourselves, we're looking to other people as gods rather than to God, which is idolatry.
At the core, people-pleasing is rooted in insecurity and a deep need for the approval of others. It is selfish because people-pleasing is, really, an attempt for the "pleaser" to feel valuable. While a people-pleaser may be a sensitive person who genuinely cares about making others happy, it can easily go awry when the pleaser enables another person to continue an unhealthy lifestyle or sin, for instance, by making them feel good instead of challenging them to righteous living.
Arguably the most awful part of people-pleasing is how it keeps us trapped within our own selves, unable to be all that God has planned for us to be. It causes us to keep our mouths shut when we should be using them to speak truth rather than flattering words. It makes us feel threatened when we do speak, because we worry we will lose the favor of others that we have worked so carefully to cultivate. Rather than rest secure in Christ, we live anxiously seeking the approval of others.
As is the case with any area of sin that the Lord reveals to us, the first step to freedom from people-pleasing is to confess it as sin and ask for God's forgiveness. Then we need to replace our misguided people-pleasing tendencies with the truth of God. Increase in your knowledge of God. Read the Word, pray, fast, and seek to know God more. We are less prone to people-pleasing when we accurately understand God's character and His demeanor toward His children. We must renew our minds to the truth of God's Word and be ready to surrender afresh to Him each day.
