Jesus was referring to the fact that, if we believe, we will have everlasting life after death.  How glorious!!  Praise! Praise! Praise!

Jesus weeped because he was empathetic and compassionate towards Mary and Martha and the other Jews who were mourning the death of Lazarus.

Jesus was so merciful, so caring and kindhearted. There were times when He was fatigued, worn and literally exhausted from his never ending duty to minister to the multitudes that were before Him. On one occurrence He tried to withdraw from the bustling surroundings to recuperate and gain his composure, but the Bible tells us that when He saw the masses who needed His help, He had great compassion upon them. He showed pity on them despite his own feelings of pain and exhaustion, He went out among the people and healed all that came to Him, and taught them all the wonderful Words of God's Kingdom of Love.--Matthew 9:36; Mark 6:31-34.

There were also times when the Lord's fury flamed through Jesus, against falsification and hypocrisy. He told the religious leaders of the synagogue filled with self-rightiousness, "If I had not come and spoken unto you, you would not be guilty of sin, but now I have come and exposed you, so you have no covering for your sin!"--John 15:22.

Most of the time He had very little to do with the upper class, the powerful and wealthy religious leaders, the Scribes and the Pharisees.--Except when they insisted on troubling Him and raising critical questions, doubts and accusations among those He was teaching. Then He poured out his rebukes against them, publicly exposing them as the "blind leaders of the blind" that they were (Matthew 15:14). These religious leaders considered themselves to be the most "righteous and holy" people in town, but Jesus laid bare the hypocrites, liars, robbers and cheaters of the poor that they were, which of course infuriated them. 

But usually Jesus avoided the self-satisfied religious, and spent His time helping and loving the poor, the common man, speaking to them, healing them, feeding them and most importantly, giving them the spiritual answers, Love, forgiveness and Truth that they longed for.
