Moses writes “these 40 years the Lord your God has been with you. You have lacked nothing.” Although the Israelites complained numerous times, God was watching over them and keeping them safe until they reached the promised land.
We can be like those Israelites, taking every opportunity to complain, or we can instead be strengthened and encouraged by the knowledge that God is also with us. We lack nothing we need to serve Him.
Jesus came into the world as light, so that whoever believed on him wouldn’t remain in darkness. Let us “believe in the light, that we may become sons of light”, that we might reflect God’s character, knowing He is watching over us.
