Abraham had no reasonable expectations Sarah would have a child based on the natural realm. Hope = reasonable expectations
Is that a English definition or from a commentary of some sort?
Abraham was called the friend of God. More than a servant. It is the same blessing that Jesus bestowed upon His disciples when he told them....
Joh 15:15 Henceforth I call you not servants; for the servant knoweth not what his lord doeth: but I have called you friends; for all things that I have heard of my Father I have made known unto you.
The writer of Hebrews used the analogy/comparison to the Immutable council of God's will in comparison to hope being an anchor of our soul.
Heb 6:16 For men verily swear by the greater: and an oath for confirmation is to them an end of all strife.
Heb 6:17 Wherein God, willing more abundantly to shew unto the heirs of promise the immutability of his counsel, confirmed it by an oath:
Heb 6:18 That by two immutable things, in which it was impossible for God to lie, we might have a strong consolation, who have fled for refuge to lay hold upon the hope set before us:
Heb 6:19 Which hope we have as an anchor of the soul, both sure and stedfast, and which entereth into that within the veil;
(I will deal with "Hope against hope" in a little while).
Another thing though came into play....God spoke....God gave a promise or a dealation. Because Abraham knew that would transcend natural realm realities (they were too old to have a child) ( I mean if God can created the heavens and the earth what is this small thing for God) that which once was unreasonable now became so.
Abraham literally lived the Gospel. That is what happens in our lives as well. The more we mature the more we are assured of the immutability of hope. (Realness in our tangible lives)
Pro 13:12 Hope deferred makes the heart sick,
When we lose hope we are doing more than just wavering. We lose all sense of direction.
Abraham was weak and listened to Sarah and had a child with the "bondwomen". Ishmael descendents now torment the children of Abraham. God's command is severe in "Cast out the bondwoman" .....
Abraham wavered. However, there was an event in the life of Abraham
Isaac had a supernatural birth. Sarah's seed was dead. Abraham's seed was dead. God literally rejuvenated their bodies. Can we imagine that one day Sarah was old and feeble and the next.... Sarah looks 40 years younger. Abraham was a wrinkled old man. One day Abraham can see better. Abraham's eyes notices Sarah and ole Abraham gets "spry and spunky".....
"Our God can do anything"
Abraham crossed the line of not just having hope.....but agreed with the declaration that God said he had made him a Father of many nations. He did not become weak in faith, in holding this belief, but gave glory to God continually that what God said was true, established and a fact regardless of what he saw or felt in the natural realm.
I wish I could get people to stop being so afraid of feelings. We are emotional creatures. God is emotion. Jesus literally weep from being hurt and exhausted from repeatedly being denied. Pain isn't absent in Divinity.
This life we live is about realizing what it is to love someone regardless of what they do. The torture of dealing with the unwilling.
I'm not trying to criticize you. Just trying to put things in perspective.
Hope is tangible in heart. Tangible in God's Immutable promises. It is where we anchor ourselves to the point of comfort and confidence (feelings).
Mind over matter? No it's not mind over matter but having FAITH in God that he changes the matter. (more could be said)
We come to point in our lives where we lose hope. The mind can not overcome this without tangible direction and meaningful comfort through the Spirit of God.
1Th 4:13 But I would not have you to be ignorant, brethren, concerning them which are asleep, that ye sorrow not, even as others which have no hope.
