Then why did you said earlier that God gave them many opportunities to be saved?
Was it really intentional or they simply happened to be there? The Pharisees and Sadducee are everywhere in those times.
Remember what Christ said He only came for the lost sheep of Israel...Did those unbelieving Pharisees belong to the lost sheep?
John 10:26
but you do not believe because you are not my sheep.
John 8:47
Whoever belongs to God hears what God says. The reason you do not hear is that you do not belong to God.”
Because the Pharisees were seeing his miracles. They were seeing people come from all over to be healed by him and to hear his teachings. Yet many were unbelieving and accused him of being in league with Satan. They had opportunities to be saved. They heard Christ's teachings, they saw his miracles, they heard of his miracles, they came from all over to see him. They had opportunities to listen. Scripture i've shown you showed you that they had opportunities. You hearing of the word of God, hearing of Christ's teachings is an opportunity in itself. The gospel is being revealed to you. So them simply hearing is a opportunity, them seeing Christ in the flesh was an opportunity, them simply talking to Christ was an opportunity.
Yes, the Pharisees were probably some of the most lost sheep of the lost sheep. According to Josephus, a Jewish historian in the time, there were about 6,000 Pharisees. They heard of Christ and came to accuse him. They heard of all the commotion. So they were there on purpose.
John 8:47
47 He that is of God heareth God’s words: ye therefore hear them not, because ye are not of God.
In John 8:41-47 God was pointing out the difference between children of satan and children of God. He was showing us how to discern those who are self righteous, who claim to be righteous, but aren't of God.
In John chapter 10 the jews, even a couple of months later, were still arguing with Jesus about what He was trying to teach them. Christ pointed out to them that they were not of His sheep and therefore weren't able to fully grasp his teachings. They were choosing to rebel. They were choosing not to believe. They were arguing with God in the flesh.
If you read further after John 10:26 he'll give you a description of his sheep. Those who choose to follow and listen.
The choice is always yours to reject Christ .. and if you reject Christ, God shows us, his sheep, the qualities that an unbeliever possess so we can discern unbelievers, self righteous men, false christians from his true sheep.
