God is sovereign like a potter with the clay. Does not the potter have power over the clay, from the same lump to make one vessel for honor and another for dishonor? (Romans 9:21). The potter is an image of God. We are like clay in his hands. The analogy of the potter illustrates the sovereignty of God. As the potter has power over the clay, so God has power over all.
God is sovereign over all creation. The Bible declares, It is He who has made us, and not we ourselves (Psalm 100:3). The potter knew nothing of an assembly line production. Each vessel was individually handcrafted. Actually, no two vessels were exactly the same. Each one was the special work of the potter. While there were categories of vessels, there was a uniqueness about each one. So, you were made uniquely by God.
God is sovereign in Christ. After the resurrection, Christ declared all power was given unto him in heaven and on earth (Matthew 28:18). That reveals the deity of Christ. Only God has power over all. God's power is revealed in our Lord Jesus Christ. Therefore, Jesus the same Lord over all is rich unto all who call upon him (Romans 10:12).
God is sovereign in our salvation. But when it pleased God, who separated me from my mother's womb, and called me by his grace, to reveal his Son in me (Galatians 1:15-16). That's how Paul became a new creation in Christ (2 Corinthians 5:17). He was transformed by the power of God in Christ (Romans 12:1-2). God's sovereignty in salvation gives all the glory to God!
