Then Peter, filled with the Holy Spirit, said to them: “Rulers and elders of the people! If we are being called to account today for an act of kindness shown to a man who was lame and are being asked how he was healed, then know this, you and all the people of Israel: It is by the name of Jesus Christ of Nazareth, whom you crucified but whom God raised from the dead, that this man stands before you healed. Jesus is:
“‘the stone you builders rejected, which has become the cornerstone.’
Salvation is found in no one else, for there is no other name under heaven given to mankind by which we must be saved.” Acts 4:8-12 (NIV)
The stone the builders rejected has become the cornerstone; The Lord has done this, and it is marvelous in our eyes. The Lord has done it this very day; Let us rejoice today and be glad. Psalm 118:22-24 (NIV)
Imagine the courage it would take to do what Peter did- to stand up to the authorities and defend his faith.
What would we do in Peter’s position? This was the same guy who had denied Jesus three times before the cock crowed (Matthew 26:75.) Yet after Jesus’ resurrection and ascension Peter had been filled with the Holy Spirit. He had supernatural courage that only God could give him to speak boldly even when such speech could cost him his freedom or even his life.
Sometimes we wonder if the Holy Spirit is still at work today. Where is that courage we need when we aren’t feeling it, or when we know we should speak up for what is right, but we don’t?
“In the same way, the Spirit helps us in our weakness. We do not know what we ought to pray for, but the Spirit himself intercedes for us through wordless groans. And he who searches our hearts knows the mind of the Spirit, because the Spirit intercedes for God’s people in accordance with the will of God.” Romans 8:26-27 (NIV)
We can be confident that God the Holy Spirit will fill in the gaps. He is strong where we are weak. That is how Peter, who betrayed Jesus three times, became a bold and stalwart witness for Him.
The Holy Spirit still intervenes for us today. He brings us back to the One Who has become the cornerstone. He gives us the courage to stand when we no longer have- or never did have- the power to stand on our own. He brings us back from a place of denial and cowardice into a place of defending our faith.
Different Christian traditions have differing views on soteriology (the “how” of salvation) but we can all agree on the Who of salvation. Whether we believe that salvation is a one-time lightning bolt event, whether we believe we choose God, or that He chooses us, or whether we believe salvation is a gradual and life-long process, the Who of salvation is not in question. It all comes back to the Cornerstone the builders rejected, the Suffering Servant (Isaiah 53:1-5) who Isaiah spoke of so long ago.
Perhaps we can agree that the Holy Spirit has endless means of grace at His disposal. After all, Saul the Pharisee- who became the apostle Paul- was knocked off his high horse on the Damascus Road. That was a pretty dramatic conversion event. Some of us have experienced dramatic conversion events as well. Others of us have gently grown into faith over the years through a series of small epiphanies and discoveries about God. God does speak to each of us differently, and we are called to respond. We can trust that when we are asked to attest to the reality and the power of God in Christ, the Holy Spirit will lead us and give us the words we need when we don’t have our own.
