In the beginning was the Word, and the Word was with God, and the Word was God. The same was in the beginning with God. All things were made by him; and without him was not any thing made that was made. - John 1:1-3
Jesus is the only begotten Son of God the Father.
God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets, Hath in these last days spoken unto us by [his] Son, whom he hath appointed heir of all things, by whom also he made the worlds; Who being the brightness of [his] glory, and the express image of his person, and upholding all things by the word of his power, when he had by himself purged our sins, sat down on the right hand of the Majesty on high; Being made so much better than the angels, as he hath by inheritance obtained a more excellent name than they.
For unto which of the angels said he at any time, Thou art my Son, this day have I begotten thee? And again, I will be to him a Father, and he shall be to me a Son?
And again, when he bringeth in the firstbegotten into the world, he saith, And let all the angels of God worship him.
And of the angels he saith, Who maketh his angels spirits, and his ministers a flame of fire. But unto the Son [he saith], Thy throne, O God, [is] for ever and ever: a sceptre of righteousness [is] the sceptre of thy kingdom. Hebrews 1:1-8
Likewise the Holy Spirit proceeds from the Father by the Son.
God is One - and yet they are different Persons.
For as the Father hath life in himself; so hath he given to the Son to have life in himself; - John 5:26
And I give unto them eternal life; and they shall never perish, neither shall any [man] pluck them out of my hand. My Father, which gave [them] me, is greater than all; and no [man] is able to pluck [them] out of my Father's hand. I and [my] Father are one. - John 10:28-30
Much more then, being now justified by his blood, we shall be saved from wrath through him. For if, when we were enemies, we were reconciled to God by the death of his Son, much more, being reconciled, we shall be saved by his life. And not only so, but we also joy in God through our Lord Jesus Christ, by whom we have now received the atonement." -- Romans 5:8-11"But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us.
So we who believe in Him "have now received the atonement." No perilous, undecided future. Our sins "have been" forgiven and we are now a "new creature in Christ."
"Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new." -- 2 Corinthians 5:17
