False teaching would lead people off the narrow path to life. That’s why Jesus warns His disciples against the deception of false teachers. Although they may look good on the outside, their evil on the inside can be seen in the fruit of what they say. The Lord will not be fooled on the Last Day, however. False teachers do not truly know the Lord now, and they will depart from Him forever.

Rev. Philip Zielinski, pastor at St. Paul Lutheran Church in Valley City, OH, joins host Rev. Timothy Appel to study Matthew 7:15-23.

“The Reign of Heaven Stands Near” is a series on Sharper Iron that studies the Gospel according to St. Matthew. The first evangelist proclaims that God has fulfilled His Old Testament promises by sending Jesus to bring the reign of the heavens among us. As the Son of David, Jesus is the gracious King we need, and as the Son of Abraham, Jesus is the blessing to all the families of the earth.

Sharper Iron, hosted by Rev. Timothy Appel, looks at the text of Holy Scripture both in its broad context and its narrow detail, all for the sake of proclaiming Christ crucified and risen for sinners. Two pastors engage with God’s Word to sharpen not only their own faith and knowledge, but the faith and knowledge of all who listen. Pastor Appel serves at Faith Lutheran Church in Godfrey, IL.

Matthew 7:15-23

A Tree and Its Fruit

[15] “Beware of false prophets, who come to you in sheep’s clothing but inwardly are ravenous wolves. [16] You will recognize them by their fruits. Are grapes gathered from thornbushes, or figs from thistles? [17] So, every healthy tree bears good fruit, but the diseased tree bears bad fruit. [18] A healthy tree cannot bear bad fruit, nor can a diseased tree bear good fruit. [19] Every tree that does not bear good fruit is cut down and thrown into the fire. [20] Thus you will recognize them by their fruits.

I Never Knew You

[21] “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. [22] On that day many will say to me, ‘Lord, Lord, did we not prophesy in your name, and cast out demons in your name, and do many mighty works in your name?’ [23] And then will I declare to them, ‘I never knew you; depart from me, you workers of lawlessness.’
