The Israelites had failed in their walk with the Lord. They constructed a golden calf during the absence of their leader (Moses) and began to worship it. Exodus chapter 32. When confronted with their sin, they repented. Chapter 33:4. Moses (who is a type of Christ) pleads on their behalf. In verse 15 Moses says "If Your Presence does not go with us, do not bring us up from here". The Lord listened to Moses as he interceded for the people. He grants Moses' request. The end result being established in Exodus 40:34.
Then the cloud covered the tabernacle of meeting, and the glory of the Lord filled the tabernacle. And Moses was not able to enter the tabernacle of meeting, because the cloud rested above it, and the glory of the Lord filled the tabernacle. Whenever the cloud was taken up from above the tabernacle, the children of Israel would go onward in all their journeys. But if the cloud was not taken up, then they did not journey till the day that it was taken up. For the cloud of the Lord was above the tabernacle by day, and fire was over it by night, in the sight of all the house of Israel, throughout all their journeys.
We need God's presence in all of our journeys. Pray always the He would go before us and make the way for us to go. Open doors, close doors, but always keep us on the path that He has established for us personally. Amen.
