Refuse any mindset that ever places you outside of God or God outside of you. Stop living as a New Creation Person with an Old Covenant, Adamic mentality. Asking God to "be with us" or attempting to "enter His Presence" is an extreme insult to the finished work of Christ.
His Presence is always a given. His Manifest Presence is enjoyed, through our fixed position in Him, as we receive His Love, bask in His Love, and respond to His Love. All things are of Him, through Him, to Him, and in Him! God was in Christ reconciling the ENTIRE KOSMOS to Himself!
As with all relationships, we must acknowledge, practice and enjoy His Presence in order to grow in our experience of His Presence. His Presence is constant. Our acknowledgment of His Presence is the variable.
