HEBREWS 2:10 For it became him, for whom are all things, and by whom are all things, in bringing many sons unto glory, to make the captain of their salvation perfect through sufferings.
1 JOHN 3:2 Beloved, 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.
Jesus Christ used to be the "only" Son of God. But not any more, according to the Bible.
Now all people who accept Jesus Christ as their Savior and Lord are also sons of God.
JOHN 1:12 But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name:
Anyone who sincerely receives Jesus is adopted into God's family.
( However, we don't begin fully mature or developed, much like human babies.)
(This is unrelated to the gender of people. We are all referred to as "sons of God," as both female and male humans have the same status with God.)
GALATIANS 3:28 There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus.
Of MANY brothers, Jesus is the firstborn, and the most significant.
ROMANS 8:29 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.
God has a family-centered plan. He's raising a LOT of boys. Even when we are infants or toddlers, we are still sons.
That God has numerous sons may seem a little weird.
It is challenging for us to accept what the Bible plainly states: that now, in light of the great redemption accomplished by our wonderful Lord Jesus Christ, He is no longer the only son of God.
This is because theologians have stressed Jesus' status as the only-begotten Son of God so much in their efforts to properly honor Him.
None of us can ever succeed Jesus as the one Lord by replacing him. He has paved the way for us to enjoy the priceless honor of also being God's sons.
SPEAK THIS: I am one of God's many sons today.
