"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. "
Do you not realize, Beloved, that you have been adopted into God's family?:
"15For ye have not
received the spirit of bondage again to fear; but ye have received the Spirit of
adoption, whereby we cry, Abba, Father. 16The Spirit itself
beareth witness with our spirit, that we are the children of God: 17And
if children, then heirs; heirs of God, and joint-heirs with Christ; if so be
that we suffer with him, that we may be also glorified together." (Romans 8: 15-17)
This adoption is not just any "sonship", though, because God sees us as "joint-heirs" with Jesus our Lord and Savior.
"For whom he did foreknow, he also did
predestinate to be conformed to the image of his Son, that he might be
the firstborn among many brethren." (Romans 8: 29)
"And he is the head of the body, the church: who is the beginning, the firstborn
from the dead; that in all things he might have the preeminence." (Colossians 1: 18)
"And from Jesus Christ, who is the faithful witness, and the first
begotten of the dead, and the prince of the kings of the earth. Unto him that
loved us, and washed us from our sins in his own blood," (Revelation 1: 5)
Jesus is the first begotten, but we who believe on His name are also begotten from death into life, and so we are brethren with Christ Jesus, seated in heavenly places with Him.
For this reason, John writes:
"Herein is our love made perfect, that we may have boldness in the day of
judgment: because as he is, so are we in this world." (1 John 4: 17)
With this full understanding of God's love, then we can know and believe:
"There is no fear in love; but perfect love casteth out fear: because fear hath torment. He that feareth is not made perfect in love." (1 John 4: 18)
You are God's child forever, because God gave us His Son. Do not fear!
