John 14: 6-7

6Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.
7 “If you had known Me, you would have known My Father also; and from now on you know Him and have seen Him.”

Hebrews 11: 1

1Now faith is the substance of things hoped for, the evidence of things not seen.

John 20: 29

29Jesus saith unto him, Thomas, because thou hast seen me, thou hast believed: blessed are they that have not seen, and yet have believed.

You can not debate faith, What someone believes. I could quote scripture to you all day long and it would not matter unless the Holy Spirit reveals the truth and you allow it in your heart. I know I am saved because of the faith that the Lord has given me and I am not the one that can convince you of things not seen. Jesus says the He is the ONLY WAY if this is not true than the whole book is worthless. It would be a lie and his words unreliable. So I choose to put my trust in my Lord and Savior Jesus Christ through faith. And if you are saved you know it in your heart because the Lord is now in your heart, you can only know this if you are truly saved. And if you know Jesus you know the Father so he is knowable. But this is through faith and if you do not posses it than you can not understand it. You see in the end when we die all will know who God is. So really this is between you and the Lord it is your choice.

Philippians 2:10-11
10That at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth;

11And that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father.

You either believe or you do not and you can think me a fool for believing, this again is your choice. I pray that the Lord opens your eyes to him. You know just as a child does not understand why their father does the things he does for him and doesn't like or understand some of the decisions he makes until he grows up. It is the same with our heavenly Father we will not understand until it is time for us to understand his ways. This is why it is called faith.
