“Fellow Israelites, listen to this: Jesus of Nazareth was a man accredited by God to you by miracles, wonders and signs, which God did among you through him, as you yourselves know. This man was handed over to you by God’s deliberate plan and foreknowledge; and you, with the help of wicked men, put him to death by nailing him to the cross.But God raised him from the dead, freeing him from the agony of death, because it was impossible for death to keep its hold on him.David said about him:

“‘I saw the Lord always before me.
    Because he is at my right hand,
    I will not be shaken.
Therefore my heart is glad and my tongue rejoices;
    my body also will rest in hope,
because you will not abandon me to the realm of the dead,
    you will not let your holy one see decay.
You have made known to me the paths of life;
    you will fill me with joy in your presence.’

“Fellow Israelites, I can tell you confidently that the patriarch David died and was buried, and his tomb is here to this day. But he was a prophet and knew that God had promised him on oath that he would place one of his descendants on his throne. Seeing what was to come, he spoke of the resurrection of the Messiah, that he was not abandoned to the realm of the dead, nor did his body see decay. God has raised this Jesus to life, and we are all witnesses of it. Exalted to the right hand of God, he has received from the Father the promised Holy Spirit and has poured out what you now see and hear. For David did not ascend to heaven, and yet he said,

“‘The Lord said to my Lord:
    “Sit at my right hand
until I make your enemies
    a footstool for your feet.”’

“Therefore, let all Israel be assured of this: God has made this Jesus, whom you crucified, both Lord and Messiah.” (New International Version)

Throughout my ministerial life, there have been individuals who have come to me a bit discouraged because they have not experienced a changed life. After trying, time and again, to be different, they say to me, “Nobody ever really changes. We’re basically the same people throughout our whole lives.”

I couldn’t disagree more.

In the New Testament Gospels, the Apostle Peter was a flake. He sometimes was discerning and got it, and sometimes didn’t. 

Peter could understand Jesus was Messiah, but then turn around and refuse that Christ had to die on a cross. He would get bold and walk on water, but then also end up afraid, needing help from drowning. Peter stood tall for Jesus, ready to take on the world, and then turn around and deny the Lord three successive times.

However, when we come to biblical book of Acts, Peter is a completely changed man. Peter gets it. He is brave and fearless. He boldly confesses Christ. And all the while he does not falter, flinch, or back down. 

So, what in heaven’s name, happened and made the difference for Peter between the Gospels and Acts? 

The Holy Spirit, that’s what, or rather, who.

God’s Spirit comes upon Peter, and he is never the same again. He is a changed man. Peter goes from flake, to fearless.

Everything falls into place for Peter, who preaches with such boldness and effectiveness that thousands turn from their previous ways of thinking and living and turn to Jesus as the hope of the world. They changed, too.

Peter was all-in with a simple and straightforward message of good news, that God raised Jesus from death. He went on to insist, without wavering and with firm conviction, that this was so, because it was not possible for the Son of God to be held by anything, even death. The proof being the resurrection.

If it was impossible for death to keep a grip on Jesus, then there is absolutely nothing that can deter Jesus or hold him back from accomplishing what he wants to accomplish. 

Flaky believers are not going to frustrate Jesus or upset his plans; he’ll just send the Holy Spirit. 

We may too often imprison ourselves in self-made spiritual jail cells. Like the pre-Pentecostal Peter, we flake and flip-flop in the Christian life. Once-in-a-while we are spot-on, but cannot really explain why, like a golfer who hits an amazing shot but can’t reproduce it no matter how hard he tries. 

The truth is that Jesus has conquered sin, death, and hell. By faith, we have forgiveness of sins in him, and have the way opened to a new life in the Spirit. It isn’t a secret; it’s a new reality.

At the front end of the Christian season of Ordinary Time, we are reminded that God’s Holy Spirit is with us. We remember what good old Peter said so long ago, which is still relevant for us today:

We have everything we need to live a life that pleases God. It was all given to us by God’s own power, when we learned he had invited us to share in his wonderful goodness. God made great and marvelous promises, so his nature would become part of us. Then we could escape our evil desires and the corrupt influences of this world. (2 Peter 1:3-4, CEV)

The message Peter proclaimed was powerful, not only because it was inherently potent, but also that the gospel dwelled mightily in Peter and inhabited a central place within him.

We, too, have that same opportunity and privilege.

Loving Lord Jesus, I confess my faults, shortcomings, sins, and rebellious acts, and ask you to forgive me. I embrace you as my Savior and Lord. Thank you for your atoning death on the cross in obedience to your Father’s will to put away my sins. Be in charge of every part of my life. Indwell and empower me with your Holy Spirit, so that I may live as your faithful follower, now and forever. Amen.
