I recommend an in depth look at what Jesus taught in public just before His awful but sacrificial crucifixion. It is recorded for all to read in John 8. The answer lies not in guesses or trying not to contradict scripture but in believing that Jesus is first and foremost for all time ('believe that I AM') just like The Father, then holding firmly to His teachings. 'Then you will know the truth and the truth will set you free.' You need to be set free from lying and angrilly hating and any immorality in this life through holding all your life to the spirit words of Jesus. He said so. You have to have a real inner knowledge of truthfulness that is found in the real spirit called The Holy Spirit in order to realise the virtue of truthfulness and to let belief in its virtue set you free from lying. The truthful speech you will be able to practice with other believers will set you free and you will realise that being like Satan is unsavoury and unnecessary and in fact all you speech can be devoted to being truthful and then angry fearful hatred can go out of the window too because it is of Satan. The freedom will be a first step towards surviving the Second Death (Revelation 19-22) and toward sanctification while you believe that Jesus truly was and is and is to come who died and truly, truly is alive. You will see Him and He and the Father will come to you and make their home with you and give the Holy Spirit to accompany you in life while you hold to Jesus' words of truth and God's words of truth.
