'Son' in the Bible

concerning his Son who was a descendant of David with reference to the flesh,

who was appointed the Son-of-God-in-power according to the Holy Spirit by the resurrection from the dead, Jesus Christ our Lord.

For God, whom I serve in my spirit by preaching the gospel of his Son, is my witness that I continually remember you

For if while we were enemies we were reconciled to God through the death of his Son, how much more, since we have been reconciled, will we be saved by his life?

For God achieved what the law could not do because it was weakened through the flesh. By sending his own Son in the likeness of sinful flesh and concerning sin, he condemned sin in the flesh,

because those whom he foreknew he also predestined to be conformed to the image of his Son, that his Son would be the firstborn among many brothers and sisters.

Indeed, he who did not spare his own Son, but gave him up for us all -- how will he not also, along with him, freely give us all things?

For this is what the promise declared: "About a year from now I will return and Sarah will have a son."
