What does John 14:14 mean? “If you ask anything in my name, I will do it.” “Moreover, he says: “I will ask the Father and he will give you another helper to be with you forever, the spirit of the truth.” (v.16,17) The asking is addressed to Jehovah God​—but in Jesus’ name. We petition God that His Son, Jesus, apply his great power and authority in our behalf.
