The singer has been told an investigation into sexual offences dating between 1958 and 1983 made by four men would be closed and no further action taken.
Sir Cliff said he was "thrilled" that the Crown Prosecution Service had decided not to bring charges after the "vile accusations".
Premier presenter Cindy Kent MBE has known Sir Cliff since 1965 and spoke about the situation on Premier's News Hour.
She said: "It has actually strengthen his faith. I was worried it would have the reverse effect, [prompting questions such as] 'Where is God?'
"But he said it had actually strengthened his faith. That is a good thing to have come out of this.
"He knows he's loved by God and he knows that God knows the truth. As far as he was concerned, he was safe in that knowledge and had nothing to prove because nothing had happened.
"God is truth and we worship him in spirit and truth and, from that point of view, he felt God was with him.
"I'm not saying he wasn't upset, because he was. But, at the end of the day, he knew he was in God's hands and that kept him going."
In a statement, Sir Cliff, 75, said: "I am obviously thrilled that the vile accusations and the resulting investigation have finally been brought to a close."
