From Beautiful Christian Life:
The visible church consists of all who profess Christ as their savior.
Yet, Jesus states,
“Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but the one who does the will of my Father who is in heaven.” (Matt. 7:21)
Jesus also tells us what the Father wills:
“For this is the will of my Father, that everyone who looks on the Son and believes in him should have eternal life, and I will raise him up on the last day.” (John 6:40)
