Jesus shows his power and authority in his teaching and in his power over the devil. Jesus continues to show that power today as he evicts the devil from people's hearts and moves in himself.
"God Reveals His Power in the Call to Faithfulness"
God sustains and powers his people to battle their enemies. The devil, the secular world, and our own sinful natures are no match for Baptism, Word, and Supper.
The call to faith shows God’s hidden power. Many reject it. For others, God’s call not only invites, but also creates the faith to do it. God calls, “Believe!” and the Word creates faith.
Jesus is revealed as the Christ (the anointed one) at his baptism as he was anointed by the Holy Spirit. In your baptism, the power of God was at work too, drowning your sinful self and raising to life a new self.
