The Redeemed Christian Church of God in Ankara is speaking after the militants, who detonated a car full of explosives at a major transport hub and interchange in the city, also injured more than 100 other people.
Turkish authorities have said the two terrorists who also died are from the banned Kurdistan Worker's Party, known as the PKK.
In response, the country bombed 18 PKK targets in the northern Iraq, the area making up part of the Kurdistan region.
Turkey's pro-Kurd party, the People's Democratic Party, condemned the terrorist attack in a statement, saying it shares "the huge pain felt along with our citizens".
The Turkish President Reccep Tayyip Erdogan and the British Prime Minister David Cameron also shared their condemnation and condolences.

I'm appalled by the devastating terror attacks in Ankara and the Ivory Coast. My thoughts are with all those affected.

Perpetual Dufu, the youth pastor of the Redeemed Christian Church of God in Ankara, told Premier's News Hour: "These are difficult times for Christians, and in these times we rely on the assurances that we have from the Bible.
"We focus primarily to be a source of comfort and reassurance to our members and for the community in which we find ourselves.
"We would be very grateful if you could join us in our prayers for increased safety and security in Ankara in generally.
"We are also praying for divine intervention in the underlying causes of this recent upsurge in terrorist activity in the country.
"And we also want to pray for the ordinary people of Turkey who bear the brunt of these attacks."
