The experiences missionaries have in meeting challenges and overcoming obstacles can strengthen them spiritually in the way that Joshua and Caleb were fortified as they conquered the land God had assigned to them.
Nii nagu Joosua ja Kaaleb said kindlust juurde, kui nad vallutasid maa, mille Jumal oli neile määranud, nii võivad ka misjonärid raskusi kohates ja takistusi ületades vaimselt tugevamaks saada.
