Psalm 15

"Yahweh, who has the right to enter your tent,
or to live on your holy mountain?"
Psalm 15:1

There is no one who has the "right" to enter God's presence expect one, that is Jesus. The description of the psalmist would exclude everyone in the Old Testament and all but one in the New. Many of us might get close in several areas but no one has them all covered.
So we do not have a right to enter God's presence but we do have an invitation. Jesus says, "Come unto me all you who are burdened and I will give you rest." Jesus invites us in as brothers and sisters, as friends to the place where God dwells.
God has gone out and searched for us to come to his banquet. We who have nor right to be there, who can never repay the invitation have been invitede to come join the party.
Who has the right? Only Jesus who invites us all to come and join him!
