"If this day you only knew what makes for peace--but now it is hidden from your eyes.”(Luke 19:42)

This was Jesus’ grieving words when he was mourning for Jerusalem. It wasn’t for the pity of the destruction of the temple where not one stone was left stacking on another, but Jesus was saddened for the hard hearts of the people.

To Jesus, the temple of Jerusalem was the house of the Holy Father, where He had stayed and preached the words of God when He was twelve. When mother Mary finally found him there, He said to her: "Why were you looking for me? Did you not know that I must be in my Father's house?" (Luke 2:49)

Despite the Pharisees and Sadducees’ discourtesy towards Jesus, the people’s eyes were as clear as snow:
“So they brought the colt to Jesus and put their cloaks over it. And he sat on it.

Many people spread their cloaks on the road, and others spread leafy branches that they had cut from the fields. Those preceding him as well as those following kept crying out: "Hosanna! Blessed is he who comes in the name of the Lord! Blessed is the kingdom of our father David that is to come! Hosanna in the highest!"  (Mark 11:7-10)

“And so I say to you, you are Peter, and upon this rock I will build my church, and the gates of the netherworld shall not prevail against it. I will give you the keys to the kingdom of heaven. Whatever you bind on earth shall be bound in heaven; and whatever you loose on earth shall be loosed in heaven." (Matt 16:18-19)

The capital of Jerusalem was totally destroyed by the Roman in the year 70, but like wisely planned; Peter had built the core of the church of the world right at the capital of Rome.

When facing today’s philosophy of physicalism and materialism, would Jesus’ words "If this day you only knew what makes for peace--but now it is hidden from your eyes.” have caused some impact deep down our hearts?
