After some years, according to Silas Shipula, who was then the church representative of the synod at that time, Yohana "appeared to have decided to serve the Lord."[19] Showing promise, Yohana was nominated by the pastor, Bartholomew Ihema, with the support of the church elders, as worthy of serving as an evangelist.
Baada ya miaka kupita kwa maneno ya Silas Shipula ambaye alikuwa mjumbe wa synod kipindi kile, Yohana “alionekana ameamua kumtumikia Bwana.”[19] Kwa uwezo aliokuwanao Yohana alichaguliwa na mchungaji Batolomeo Ihema na kubaliwa na wazee wa kanisa kuwa mtumishi alifaa kuwa mwinjilisti.
