"No man hath seen God at any time; the only begotten Son, which is in the bosom of the Father, he hath declared him." (John 1: 18)
If we want to know the Father, we have to know the Son.
We have to know that we are in the Son:
"3For ye are dead, and your life is hid with Christ in God. 4When Christ, who is our life, shall appear, then shall ye also appear with him in glory." (Colossians 3: 3-4)
We have to understand that the Son is in us:
"To whom God would make known what is the riches of the glory of this mystery among the Gentiles; which is Christ in you, the hope of glory:" (Colossians 1: 27)
We have to understand that the Son created everything:
"For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him:" (Colossians 1: 16)
Of course, the first trait which Paul lists speaks to His representative Sonship:
"15Who is the image of the invisible God, the firstborn of every creature:" (Colossians 1: 15)
You want to see the invisible God, you see the Son in the Word of God.
Now, because you are in Christ, and as He is, so are you (1 John 4: 17), you can know and believe that you are in the Father's bosom, too:
"1Behold, what manner of love the Father hath bestowed upon us, that we should be called the sons of God: therefore the world knoweth us not, because it knew him not. 2Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is. 3And every man that hath this hope in him purifieth himself, even as he is pure." (1 John 3: 1-3)
Today, rest in the truth that you are in the Father's bosom, that He loves you as much as He loves Jesus (John 17: 21)
