Exodus chapter 13

21 By day the Lord went ahead of them in a pillar of cloud to guide them on their way and by night in a pillar of fire to give them light, so that they could travel by day or night.
22 Neither the pillar of cloud by day nor the pillar of fire by night left its place in front of the people.


The people knew that God was with them because they had the physical signs of the pillar of cloud by day and the pillar of fire by night. Two signs that meant God was with them, no matter what time of the day or night as they could see his presence.

So what about us Christians today? What do we have so we can know that god is with us day or night? Well, we have the Holy Spirit, we are sealed by the Holy Spirit the second we become Christians and accept Jesus as our Lord and Saviour, and we have our hearts filled by Him. He is the comforter, the guide, who is always with us and we need to learn to listen for his leading, his prompting, his guiding. We also have the Bible, the word of God, to teach us, help us, explain things to us, show us the things that have been and the things to come. The Holy Spirit helps us understand the bible when we ask him to open our eyes our hearts and our minds.
We may not feel the tangible presence of God with us each and every waking moment. There may be times when we feel so alone, so lost, as if there is no one who really cares, yet God is with us then too. We need to trust in Him, to look to His word for reassurance and comfort, and not rely on our own feelings. The enemy is a liar, and the father of lies, and he will do all he can to get us to turn away from God, to believe we are on our own, that God has left us to it. Didn't Jesus tell the disciples, and us, that he will be with us even to the ends of the age (Matthew 28:20)?

Jesus committed no sin at all, so he would not, could not lie, and if that is the case, then we are absolutely, never, ever alone. Just as God never left the Israelites whilst they were in the desert, so He never leaves us.
