You are not a Christian because you go to church. You are also NOT not a Christian because you don't go to church. However, if you are a Christian, it makes sense that you would want to hang out with other Christians, learn from other Christians, help and support other Christians, be helped by other Christians and value time that allows you to grow in your relationship with Jesus.
Lord, thank You for providing opportunities to know You more fully and help me to take advantage of those opportunities.
