Joh 10:30 I and the Father are one."
Joh 14:9 Jesus said to him, "Have I been with you such a long time, and do you not know me, Philip? He who has seen me has seen the Father. How do you say, 'Show us the Father?
Joh 14:11 Believe me that I am in the Father, and the Father in me; or else believe me for the very works' sake.
Jesus and God are one as we are made one with Christ, there is no difference in the two. The identification of Father is reality of who Christ was, He was the Son, God incarnate, Alpha and Omega. Otherwise the first verse of John is wrong or he was mistaken as to what the comforter was telling him.
Joh 1:1 In the beginning was the Word, and the Word was with God, and the Word was God.
Joh 1:2 The same was in the beginning with God.
Joh 1:3 All things were made through him. Without him was not anything made that has been made.
Joh 14:26 But the Counselor, the Holy Spirit, whom the Father will send in my name, he will teach you all things, and will remind you of all that I said to you.
In this verse you see the three are one, and all originate from the same source, being God the Father, but they are both given authority in the Father's name, another distinction of sameness and oneness.
(Joh 15:13) Greater love has no one than this, that someone lay down his life for his friends.
(Joh 15:14) You are my friends, if you do whatever I command you.
(Joh 15:15) No longer do I call you servants, for the servant doesn't know what his lord does. But I have called you friends, for everything that I heard from my Father, I have made known to you.
(Rom 10:8) But what does it say? "The word is near you, in your mouth, and in your heart;" that is, the word of faith, which we preach:
(Rom 10:9) that if you will confess with your mouth that Jesus is Lord, and believe in your heart that God raised him from the dead, you will be saved.
(Rom 10:10) For with the heart, one believes unto righteousness; and with the mouth confession is made unto salvation.
These verses together, illustrate that it is not by works, by religious piety, or self-inflicition but by grace alone are we saved through Christ. Christ laid down all He had for His sheep, for the world. He did not lay out any claims as to what necessitated salvation, but Paul makes it clear that it is by belief in the heart and confession of the mouth that salvation is received, and this is the only way. Anyone who tells you any other way should not be received but to be rebuked over their false "truth".
1Pe 3:15 But sanctify the Lord God in your hearts; and always be ready to give an answer to everyone who asks you a reason concerning the hope that is in you, with humility and fear:
This last verse is a requirement of the brethren to those who exist in darkness and live separated from the Lord. We must stand ready and able to answer all questions of the Truth. Peace to all, and that peace can only reside in the one whom God sent as sacrifice for the sins of the world.
