Not everyone who says to me, Lord, Lord, will enter the kingdom of heaven, but only the one who does the will of my Father in heaven.
What is the will of the Father???
To follow the teachings of Christ.
It means actively living the word.
Declaring that you believe is insufficient, as is made clear in Matt 7: 21-27. You must also live and act consistant with those professed beliefs. If you do not, Christ will rebuke you.
