In my experience, everyone has serious issues with their spiritual life.
Yes and no.
If someone is reading the Word, meditating on it, and praying on a regular basis, they are getting spiritually fed on a regular basis and don’t *need* church.
People don’t eat one huge meal a week and expect it to sustain them or consider it an adequate diet. They don’t talk to their spouse or child once a week and consider it a healthy relationship.
A person’s relationship with God should not be so dependent on church and when it throws someone so for a loop because they missed church, yeah, I still contend that they have some serious issues with their spiritual lives.
