Psalm 21:6

Surely you have granted him eternal blessings and made him glad with the joy of your presence.

Many days are filled with anything but joy in this world.  Our only source of joy that will never change is Father God, Savior Jesus, Holy Spirit!  His presence goes before us and along side us and has our back through everything and anything we walk through on this earth.  Take joy in Him, He does not change like shifting shadows! (James 1:17)
