It is not because of your righteousness or your integrity that you are going in to take possession of their land; but on account of the wickedness of these nations, the Lord your God will drive them out before you, to accomplish what he swore to your fathers, to Abraham, Isaac and Jacob.
Deuteronomy 9:5 NIV
It is interesting to see the Ancient of Days, the God of the Old Testament and New Testament, which some people have difficulty reconciling together. Deuteronomy 9 shows two character traits that span the Old and the New. First, God's favor is not based on our merit but on His grace. Second, His promises for us are fulfilled not by turning to our own strength and our own abilities, but rather they are fulfilled when the Lord our God accomplishes them in His strength and by His abilities. As the Lord told Zerubbabel in Zechariah 4:6, "Not by might nor by power, but by my Spirit," says the Lord Almighty.
Turn to God's grace rather than trusting in my merit, and praise Him for showering His grace upon me. And do not rely on my strength and abilities, but rather trust in God's strength and His abilities. Know that His ways are not my ways; they are much higher than my ways.
Lord, it is so easy for me to get smug in the favor You have blessed me with. It is so easy when things go well to say, "I did that." But I remember that it is Your grace showered on me that brings favor, and it is Your power and might at work which accomplishes results. I rest in Your grace and in Your power. Use me and bring me into the work You are doing so that I may be a part of it. Help me to see You all along the way so that I do not take credit or get proud. I love you!
