‘Does a Christian have to attend every service his church provides? The simple answer is “no.” There is no New Testament command for believers to maintain perfect attendance at church. Attending every church service does not make a person “holier” than the one who misses a service here and there. Our relationship with God is not based on rule-following or punching a time clock at church; it’s based on our position in Christ (1 Corinthians 1:2). The question that matters in eternity is not “How many times was I in church” but “Did I truly know Jesus Christ?” (Matthew 7:21–23).
‘However, there is a problem with having a nonchalant attitude toward church attendance. We should not be ambivalent in the matter. God’s plan in this age involves the church, which Jesus promised to build (Matthew 16:18), and we should be supporting God’s plan enthusiastically.’
