Heaven is where God is and where God is that's heaven. God is the light of our life and without Him darkness prevails everywhere.
The disciples of Jesus were filled with great joy in His presence, for God's presence really filled their life with light so much that they had no time and need to fast for the removal of darkness, however they did have to face criticism for this from the Pharisees who ritualistically tried in vain to remove the own darkness.
Jesus replies to their question of why His disciples were not fasting...
'But the days will come when the bridegroom will be taken away from them; then they will fast in those days.'' Luke 5:35 (NKJV)
The Psalmist said wonderfully...
' Oh, taste and see that the LORD is good;
Blessed is the man who trusts in Him! ' Psalm 34:8 (NKJV)
Yes!!! Its truly great and blessed to experience God in our life, to taste His blessedness for then we will know that nothing can ever satisfy us as God would.
After Jesus was taken away from the world, the disciples did miss Him, they missed His love & concern, they missed His compassion, they missed the heart of the Father.
God did not leave them alone, but filled them with His Holy Spirit through Whom they did great and mighty wonders for Him.
Now followed the time of prayer, devotion, fasting and the deep yearning for God which was easily available when Christ was with them in person.
Now they were not ignorant of the fact that Christ was still with them, was in them and worked through them.
Let all we do lead us to the blissful experience of knowing the goodness of the Lord and the joy of His presence.
Let's know Him and then we will do anything and everything to know Him more and more, for there is no one like Him, Jesus Christ is the heaven we would always desire to be in.
