The Greek that is translated as “character” (or “experience”) in English is translated in the following ways:

• Pitjantjatjara: “we become with strength and don’t fall, and God seeing us is pleased” (source: Carl Gross)
• Hopi: “maturity”
• Isthmus Zapotec: “standing firm”
• Central Tarahumara: “being called as doers of good”
• Miahuatlán Zapotec: “showing people we really believe in Christ”
• Central Mazahua as “knowing that we passed well” (source for this and four above: Waterhouse / Parrott in Notes on Translation October 1967, p. 1ff.)
• Bariai “God is happy with us because we overcome/surpass various kinds of testings” (source: Bariai Back Translation)
