We know why God asked that of Abraham. It was a one time command. Because the Holy Spirit is the One leading us, we also know that it won't be asked of us. Christ became our sacrifice once and for all. Some of us may be called to give our own lives for Christ.
And what is that called? That is not sacrifice?
John 21:18 Verily, verily, I say unto thee, When thou wast young, thou girdedst thyself, and walkedst whither thou wouldest: but when thou shalt be old, thou shalt stretch forth thy hands, and another shall gird thee, and carry thee whither thou wouldest not.
John 21:19 This spake he,
signifying by what death he should glorify God. And when he had spoken this, he saith unto him, Follow me.
Paul faced that possibility this way:
6Therefore we are always confident, knowing that, whilst we are at home in the body, we are absent from the Lord: 7(For we walk by faith, not by sight: ) 8We are confident, I say, and willing rather to be absent from the body, and to be present with the Lord. 9Wherefore we labour, that, whether present or absent, we may be accepted of him.
2 Corinthians 5
I would say Paul was more poignant:
2Tim 4:6 For
I am now ready to be offered, and the time of my departure is at hand.
2Tim 4:7 I have fought a good fight, I have finished my course, I have kept the faith:
2Tim 4:8 Henceforth there is laid up for me a crown of righteousness, which the Lord, the righteous judge, shall give me at that day: and not to me only, but unto all them also that love his appearing.
Dan 9:27 And
he shall confirm the covenant with many for one week: and in the midst of the week he shall cause the sacrifice and the oblation to cease, and for the overspreading of abominations he shall make it desolate, even until the consummation, and that determined shall be poured upon the desolate.
By him therefore let us offer the sacrifice of praise to God continually, that is, the fruit of our lips giving thanks to his name.
Hebrews 13:15
See Hebrews 13:16 below.
See also Hebrews 5:
Heb 5:1
For every high priest taken from among men is ordained for men in things pertaining to God, that he may offer both gifts and sacrifices for sins:
Heb 5:2 Who can have compassion on the ignorant, and on them that are out of the way; for that he himself also is compassed with infirmity.
Heb 5:12 For when for the time ye ought to be teachers,
ye have need that one teach you again which be the first principles of the oracles of God; and are become such as have need of milk, and not of strong meat.
Heb 5:13 For every one that useth milk is unskilful in the word of righteousness: for he is a babe.
Heb 5:14 But strong meat belongeth to them that are of full age, even those who by reason of use have their senses exercised to discern both good and evil.
