Rev Les Isaac, who delivered the sermon at last week's National Parliamentary Prayer Breakfast, sponsored by Premier, has said the event reminded him about the power and authority of God.
He was responding to Sajid Javid saying the sermon led him to resign as health secretary last week. Mr Javid's decision to quit triggered 60 other government resignations, as well as the prime minister's.
In an interview on Premier's podcast A Mucky Business with Tim Farron, Rev Isaac said: "It's important for all of us as ministers, men and women who preach publicly to recognise that, in our words, is not just a good homily, a good sermon.
"God's authority, God's power, God's Spirit is at work in and through us. And I think for me, it makes me think more about the need to hear God's voice, and to be a channel, a conduit so that God could speak to men and women whoever they are, wherever we are.
"We've got to recognise that once we stand up to deliver that scripture that word of God, that there's the potential of changing people's lives, changing people's attitude, changing people, in terms of the decisions that they've made. For me, it was an encouragement to hear that."
On Sunday, Mr Javid revealed he had been wrestling with his conscience for months but that a sermon by Rev Isaac had prompted him to take action.
"I made my decision then, sitting there listening to his sermon, and I just thought, it's about integrity, it's about a duty. If you haven't got confidence in the boss, you owe it to yourself and the country to tell the boss nicely that you can't serve and that was it."
The Street Pastors founder and president of Ascension Trust told Mr Farron about the need for integrity and humility in all walks of life.
"Whether you're in politics or the Church, or you're a school teacher or police officer, there's something about society's expecting that we have to be men and women of integrity, what's on the tin has got to be inside and played out in public or in private," he said.
"It means that what we say people are listening to us, it means that what we do, people are watching us. And when we say it or do it, people will copy and emulate us. And so it is important that we get it right in terms of integrity".
"I know that we're human beings, and all of us have our flaws and our weaknesses. But…humility helps us to say, 'Sorry, I got it wrong, please forgive me'. And you show that sort of remorse. that contriteness and I think that those two things go together, definitely in politics, definitely ministry. and in any place of power authority we need those two things."
