God guided His people out of Egypt with a cloud and a pillar of fire. The cloud was for the day. The fire for the night. The visibility of the people affected how they would see God’s presence. Even though God was always there and always the same God, the way the people viewed him was different.
Maybe you’re going through something and you’re wondering where God went. He hasn’t left you. He is still there guiding you. Your circumstances may have changed, which could have caused your vision to be altered. Ask for Jesus to help you see His presence in your situation.
