The writer to Hebrews would encourage you to diligently come to realise 'the full assurance of hope'
'Insurance' is something that may or may not happen. 'Assurance' is something that 'will' happen.
Insurance 'might' pay out, but Assurance 'will' pay out.
Heb 6:11 And we desire that each one of you show the same diligence so as to realize the full assurance of hope until the end,
Heb 6:12 so that you will not be sluggish, but imitators of those who through faith and patience inherit the promises.
The writer to Hebrews goes on to show why we can have full assurance of our hope.
Firstly, that the promise was made by God, who swore the oath to Himself.
It was not made between God and man, for we all know that man will fail to keep the oath.
The promise cannot fail, because God cannot fail.
Secondly, God cannot lie.
Heb 6:13 For when God made the promise to Abraham, since He could swear by no one greater, He swore by Himself,
Heb 6:14 saying, "I WILL SURELY BLESS YOU AND I WILL SURELY MULTIPLY YOU."
Heb 6:15 And so, having patiently waited, he obtained the promise.
Heb 6:16 For men swear by one greater than themselves, and with them an oath given as confirmation is an end of every dispute.
Heb 6:17 In the same way God, desiring even more to show to the heirs of the promise the unchangeableness of His purpose, interposed with an oath,
Heb 6:18 so that by two unchangeable things in which it is impossible for God to lie, we who have taken refuge would have strong encouragement to take hold of the hope set before us.
It is Christ in you, that is the hope of glory.
Heb 6:19 This hope we have as an anchor of the soul, a hope both sure and steadfast and one which enters within the veil,
Heb 6:20 where Jesus has entered as a forerunner for us, having become a high priest forever according to the order of Melchizedek.
Christ is the Rock of our salvation, and if our anchor is on the Rock, our soul will realise the full assurance and we will be steadfast. If the anchor is in ourselves, it is like having the anchor in the boat, and we will be tossed about on the waves.
God cannot lie, and God cannot fail
