'Today' in the Bible

For to which of the angels did he say at any time, "You are my Son. Today have I become your father?" and again, "I will be to him a Father, and he will be to me a Son?"

Therefore, even as the Holy Spirit says, "Today if you will hear his voice,

but exhort one another day by day, so long as it is called "today;" lest any one of you be hardened by the deceitfulness of sin.

while it is said, "Today if you will hear his voice, don't harden your hearts, as in the rebellion."

he again defines a certain day, today, saying through David so long a time afterward (just as has been said), "Today if you will hear his voice, don't harden your hearts."

So also Christ didn't glorify himself to be made a high priest, but it was he who said to him, "You are my Son. Today I have become your father."

Jesus Christ is the same yesterday, today, and forever.
