Joh 14:6 Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.
Jesus is the truth. He truly came. He truly taught. He truly died. He truly rose again from the dead. He truly sits in heaven at God's right hand.
Does that mean that everything which is taught in His name today is true?
If He taught it, it is true. But if He didn't teach it...
Have you ever asked God to show you the lies which you have believed?
If not, are you willing to ask? You will surely be surprised at His answer.
If you are willing to have your faith challenged, to find the idols in your life, to embrace the truth, ask.
You will be changed. You will become more like Him.
