Things not seen
Why do we have to pray to God about all the promises in his word? He has promised so why can’t He just do it. It is again this word faith which everything pivots around whether we like it or not, In Hebrews 11:1 we can dig for the treasures buried there; “1Now faith is assurance of things hoped for, proof of things not seen. 2 For by this, the elders obtained testimony. 3 By faith, we understand that the universe has been framed by the word of God, so that what is seen has not been made out of things which are visible.”
First; faith is assurance of things hoped for, “things hoped for” is all the promises in the Bible, however, before that, you have to establish the foundation, namely that all the words in the Bible are from God, every single one of them, you cannot blame the translations, because you can always go to the Interlinear Bible and look at the Hebrew text in The Old Testament and Greek in The New Testament. First then when you have decided in your heart that the words in the Bible are from God, then you can start digging for the true treasures buried in the Word.
We cannot sense them
Back to faith in Hebrews 11:1; Assurance is what happens in your heart, not in your brain, it is influenced of what you daily are thinking about, but for the assurance to be established in your heart it takes time, the longest distance you ever “walk” in your life is from your brain down to your heart. “and evidence of things not seen” it doesn’t say things that are not, no those things not seen are in a perfect shape and in a perfect world, not like this imperfect world that we can see. Our problem is that we cannot sense them, not see them, not touch them and we don’t like that, we want to confirm it by our senses, however, that is not faith.
By His marvellous name.
Salvation also is spiritual, Jesus is a powerful spiritual name, which can change your heart over to the heart of Jesus, however it takes faith in the Words of God, these words spoken by God is pure power, they hit you like a sword and cuts out your dirty heart and puts in a new one. Lean to the Word not to your own understanding. For with the heart, one believes resulting in righteousness; and with the mouth confession is made resulting in salvation. Just admit you are a sinner and Call on His marvellous name and ask Him to fill you with His Holy Spirit, then you are transferred over to His kingdom.
