Yes Jesus taught the same thing as to have in you the same Father he had in himself see John17 and you are so correct those religious folk didnt give Jesus the time of day for teaching the same thing either. For they did worship a different godf from the one jesus said he was of, same One I am of.Then talk about those symptoms of false doctrines, because no one is going to give you the time of day when you say they have a "different god." As a teacher, you are your own worst enemy, so stop that line of teaching.
Change my strategy? All I can do is be honest and repeat what Jesus said that who I am in the Father for what Jesus said we should be in Him as he was in Him. I dont know any other strategy than what Jesus said we should be.They don't have a different God, they just don't understand the one they have. Combat the false teachings of "we will always sin until after death," "we can't be perfect until after death," "we can't be glorified until after death," etc. Jesus came to make us like Him NOW! I agree with your doctrines that combat the false doctrines, now change your strategy.
Do you have a different strategy aside from the way of Jesus Christ who stirred people to the point of hatred, scandal, lies, to crucifying him for blaspheme?
