It ought to be our goal to find favor with God, and, if possible, with people. The early Christians did not always enjoy favor with people (which was apparent when they were being thrown to the lions), but they did experience God’s approval.
When our focus is properly on God, the world around us will often be attracted to Him too. When people see our genuine devotion to Christ and they observe the positive difference He makes in our lives, they will inevitably want to know our God also.
Sometimes our worship can be self-centered. It becomes all about us and what we like or what makes us comfortable. The songs we sing are about what God does for us and how happy He makes us feel. At other times our worship can become about others. That is, we become more concerned with the comfort of the unbelievers who are attending our services rather than being focused on pleasing God through our worship.
Worship is fundamentally about God and who He is and what He was done. When we focus on Christ and praise Him with all of our heart, God will inevitably add people to our fellowship. Just because we like our worship services does not mean that God does. Just because visitors enjoy our worship does not mean God does. One of the ways to determine if God is pleased with the manner in which we are relating to Him is by looking to see if God is adding people to our number.
