There is one main underlying theme in all of these verses. We can’t do this alone. We can’t try to fly solo in life and trust in our own feelings or beliefs to get us through. Every time throughout Biblical history that the people of Israel fell away from God and tried to do things on their own ended up in some sticky situations and went crawling back to God for help. Had they just stuck with God all along, they may not have ever gotten into those sticky situations. In Psalm 90, the writer is crying out to God to always be there and to guide him. In Deuteronomy, Moses tells us that people turned from God despite all that he had done for them. He reminds the Israelites about how God has been faithful and true to them, and calls his people to remain true to God. And in Titus, the writer, Paul, reminds us that God’s grace came to us in the form of Jesus, who provides salvation for all who believe.
Today and always, remember who you truly need to rely on each and every day. It is so easy to get caught up in the trap that you (we) can accomplish so much because of our own talents or, dare I say, greatness. But our talents alone will only get us so far. We NEED God on our side. So, in conclusion, trust in the Lord.
