“Not everyone who calls out to me, ‘Lord! Lord!’ will enter the Kingdom of Heaven. Only those who actually do the will of my Father in heaven will enter.” (Matthew 7:21, NLT)
When valued against actions, talk is cheap.
Jesus says that it is not just our confession, but it is through our obedience to God’s law that we realize the rule of God. Furthermore, as we see in the two verses that follow (verses 23 and 24), it is not our successes that impress our heavenly Father; it is our faithfulness.
How different is that from what we see daily: Where good words are often divorced from good deeds? Give God the lead today — and faithfully follow! – Luther
