Jesus is the truth! And Jesus is the Word who was in the beginning with God and is God! So it is a bit confusing when you write He is the ideal of the truth? He is the truth - I don't understand why or for what reason 'the ideal of' is in the OP? Also I don't understand what you mean by "can you say me it"?
What I can say (or write in this case) is that Jesus Christ is the Lord our God. We can hear from Him via His Holy Spirit talking to our spirit. So His words are spirit and His sheep hear those words He has for us. Those words include teachings, wisdom, knowledge, instructions, and more. So we can and should be following Him via His voice (the Holy Spirit speaking to us is words we pick up in our heart and sometimes on our lips) He explained this: That His sheep hear His voice, that He leads them out with His voice, that His words are spirit and are life, and so on. So that is what it means to be a Christian! We follow Jesus Christ; the Truth, the Word, the King of kings, and God.
