The Greek adjective anupokritos means sincere, genuine, or without hypocrisy — literally 'un-hypocritical.' Appearing 6 times in the New Testament, it is always used to describe the authentic, undivided quality of love, faith, and wisdom that God desires and the Spirit produces.
Anupokritos is formed from a- (without) + hupokrisis (hypocrisy, acting under a mask). In Greek theatre, a hupokritēs was an actor who wore masks — and Jesus applied the word scathingly to the Pharisees who performed religion for human approval while their hearts were far from God. Anupokritos names the opposite: genuine, mask-free reality. Romans 12:9 commands: 'Love must be sincere (anupokritos).' James 3:17 describes heavenly wisdom as 'first of all pure; then peace-loving, considerate, submissive, full of mercy and good fruit, impartial and sincere (anupokritos).' Paul uses it to describe Timothy's 'sincere faith' (2 Timothy 1:5) and the 'sincere faith' that lived first in his grandmother Lois and mother Eunice. 1 Peter 1:22 commands sincere love 'from the heart.' This word challenges every performance of Christianity and calls for the undivided, unmasked devotion that God alone truly sees.
