The third step for Christians to take is to be "Barnabases", according to Azumah, who said that personal testimonies are more powerful when people know the one involved.
He used the story of the Samaritan woman recorded in John 4 as a case in point, noting that the Bible records how "many of the Samaritans from the town believed in him (Jesus) because of the woman's testimony" (John 4:39).
Samaritans, Azumah said, were to Jews as Muslims are to Christians.
But Azumah noted that even as a believer gets to know a Muslim, testifies to them and demonstrates the love of God to them with their life, ultimately the change takes place through the power of the Holy Spirit.
"Wait upon the Lord!" Azumah urged, citing from Ephesians 6.
"You might have the resources; you might have enthusiasm and all the knowledge, but wait for the Holy Spirit to come to you," he exhorted. "It's a spiritual business."
Before concluding his address, Azumah urged Christians to offer four prayers to God for the advancement of the Gospel in the Muslim world.
"First, pray for ourselves for a heart for Muslims. Second, pray for Christian minorities in the Islamic world. Third, pray that God may open up the Muslim world for the Gospel. Finally, pray for individual ordinary Muslims wherever they may be," he said, adding that he had prayed for his uncle for 15 years before laying hands on him and baptising him three years ago.
"Many Muslims come to Jesus Christ through visions and dreams," Azumah pointed out. "God is doing it."
Though Muslim countries can deny missionaries visas, "the Holy Spirit does not need a visa", he said, drawing the applause of the crowd.
"He goes where he wants to go," he added. "If we pray with Muslims as our prayer topic, the Holy Spirit will go."
In closing, Azumah urged Christians to step up in response to the challenge of Muslim evangelism; step out of their comfort zones, even their churches and denominations; and step into Muslim neighbourhoods, Muslim countries, and the Muslim world.
Azumah said that more than 80 per cent of Muslims have never heard the Gospel and less than one per cent of the Christian missionary force works among Muslims.
Last week's Inside-Out Conference, hosted by the Presbyterian Global Fellowship, was the third annual conference held in response to the decline of the Presbyterian Church (U.S.A.) and the controversies that have kept the denomination embroiled in internal battles over the year.
It was the hope of a group of leaders to begin to change the culture of the Church by being "inwardly strong and outwardly focused".
