This was all I could think of this morning. Here are some descriptions. In union with God, you and God become one, totally inseparable. You are God are in each other and belong to each other. Wherever God is, you are. You are aware of God dwelling within your heart. You and God share the same joys and sorrows; are in perfect harmony because his will and yours are the same. You enjoy his perfection, holiness, and beauty. It's eternal love. It's reality, no fantasy. Without union, your spiritual journey will be laborious. With union, it becomes effortless because God carries you all the way. Union is possible because it's all God's doing with your consent. Union with God is the ideal and perfect state of existence for us because it is precisely what God desires.
