About

David & Sandra Macmillan grew up in the shadow of Table Mountain. Their lives changed in a big way in 1980 when they left South Africa to carry the great news about Jesus to the ‘Land of Smiles’, Thailand.

After two decades of fulfilling ministry that stretched and shaped them more than they thought possible, the Lord signaled a new season for them: Wingspan was born.

Wingspan is a prayer mobilizing, teaching and training ministry.

Growing in prayer is a lifestyle and mission adventure designed for all of Christ’s followers, a journey much too good to miss. It’s one guaranteed (by the Lord) to be enjoyable, extraordinary, to advance his kingdom and (most importantly) draw attention to the kind of God he is (his glory).

About the words in the Wingspan logo, Shaped to soar: The Spirit of Christ is constantly at work in his followers, strengthening and stretching our spiritual ability to go higher in knowing him and further in praying him known.
