This Scripture reading is typically used for Palm Sunday. However, from this passage, we need to see a commentary on the purpose of Christ's coming to earth.

• Luke 19:28-38 - Christ confidently fulfilled the Scriptures that were written of Him.
• See Matthew 21:1-5; Zechariah 9:9; Isaiah 62:11 cp. John 12:12-16.
• In Luke 19:37-38 Jesus was honored as a King - One who would bring Salvation to them. In Matthew 21:8-9, "Hosanna" means "save now." This is a fulfillment of Psalm 118:25-26.
• The triumphal entry of Christ is also connected to the complex prophecy of Daniel 9:24-26.

Time and space do not allow an explanation to be given here. Please consult John MacArthur's Study Bible (Matthew 21:9) and his New Testament Commentaries. Also read "Daniel's Prophecy of the 70 Weeks" by Alva J. McClain (BMH Books); and "The Coming Prince" by Sir Robert Anderson (Kregel Publications).

• Luke 19:39-40 - Christ is publicly acknowledged as Israel's king before an enormous multitude. The Pharisees attempt to stop this, but Jesus tells them it is impossible to stop this moment. There is no way to avoid the fact that the King has come, even though He will be rejected by His people in a short while.
• Luke 19:41-44 - Christ, "the man of sorrows," weeps over Jerusalem and foretells of the sufferings that will come upon them.
• Luke 19:45-46 - Christ purges His Father's house and calls them to pure worship.
  See John 4:23-24.
• Luke 19:47-48 - Christ is the object of the hatred of Israel's leaders, but they are stifled by the popularity He has with the common people. They underestimate what will happen when they put Him to death. See Psalm 118:22-23 cp. Luke 20:1-19 & etc.

So, Jesus came, and it was a problem for the religious leaders of Israel. The problem was unavoidable because divine power and authority was with Him. Not believing this, the enemies of Christ underestimated the results of their plans to destroy Him. See Psalm 2:1-12.

Christ's coming was unavoidable!

• The Pharisees were exasperated. "…You see that you are accomplishing nothing. Look, the world has gone after him!" (John 12:19)
• God's providence had made an appointment that no man could cancel. (Thank God!)
• "But when the fulness of the time was come, God sent forth His Son, made of a woman, made under the law, to redeem them who were under the law, that we might receive the adoption of sons." (Galatians 4:4-5)
• We have another appointment that we cannot cancel. "And as it is appointed unto man once to die, but after this the judgement: so Christ was once offered to bear the sins of many; and unto them that look for Him shall He appear the second time without sin unto salvation." (Hebrews 9:27-28)

Christ's coming was underestimated!

Those who led the people to cry "…We have no King but Caesar." (John 19:15), and "His blood be on us and on our children." (Matthew 27:25), would later complain to the Apostles that they "intend to bring this man's blood upon us." (Acts 5:28). Other Jews would complain that those who preach the Gospel have "…turned the world upside down…" (Acts 17:5-7).

It is well described, as the old spiritual is sung, "Sweet little Jesus boy, born in a manger, Sweet little Holy child, we didn't know who you was…"

• They underestimated His words. Jesus was called a blasphemer and a mad-man - possessed with a demon, but they underestimated that He was actually telling the truth.
• They underestimated His power. The leaders of Israel and Satan himself thought that if they could only kill him, their problems would be over, but they underestimated that He would rise from the dead and have eternal power over sin, death, hell, the world, and the universe. See John 10:15-18; I Corinthians 2:7-8; Colossians 2:12-15; Acts 2:22-36; 4:24-28; 17:30-31; Revelation 1:4-18.
• They underestimated the Gospel's power. Those who hear the Gospel and wish to stop it are underestimating the power of the Gospel and of the Holy Spirit. See Matthew 24:14,35; 28:18-20; Acts 4:8-20 (cp. Philippians 3:18-21); Romans 1:1-4,14-16; 10:17; I Thessalonians 1:5; II Timothy 2:8-10 (cp. Isaiah 55:6-11); Revelation 12:10-11 (cp. Romans 16:20).

Though Satan and the kingdoms of this world seek to destroy the knowledge of the Gospel (II Corinthians 4:3-4) "… the earth shall be filled with the knowledge of the glory of the LORD, as the waters cover the sea" (Habakkuk 2:14).
