There is little that separates humans from other sentient beings - we all feel joy, we all deeply crave to be alive and to live freely, and we all share this planet together.
The joy of the Lord will arm us against the assaults of our spiritual enemies, and, put our mouths out of taste for those pleasures with which the tempter baits his hooks.
God will never plant the seed of his life upon the soil of a hard, unbroken spirit. He will only plant that seed where the conviction of his spirit has brought brokenness, where the soil has been watered with the tears of repentance as well as the tears of joy.
