“Here I stand, knocking at the door. If anyone hears me calling and opens the door, I will enter his house and have supper with him, and he with me” (Rev 3). Jesus entered Zaccheaus' house even though Zaccheaus was called a sinner (Lk 19). The one thing Jesus asks is that we be willing to open the door.
Jesus himself teaches us how to pray. Having Jesus as a guest begins with paying attention to the movement of his Holy Spirit in our hearts, drawing us into prayer. This happens often with Jesus' disciples. Whatever we may have on our minds Jesus wants to accomplish his own plan in us. He is interested in bringing us into closer union with himself and with his Father in the Holy Spirit. That will last whatever our passing concerns may be. He is not indifferent to those concerns. However, he has priorities which are more lasting than our plans or concerns of the moment.
Lord Jesus, enable me to let go for a time of anything which can disturb my peaceful union with you. I believe that you will be with me later in dealing with my problems if I set them aside now so as to be with you in a communion of love.
