Romans 3:25 English Standard Version (ESV) whom God put forward as a propitiation by his blood, to be received by faith. This was to show God’s righteousness, because in his divine forbearance he had passed over former sins.
Propitiation means acceptable substitute, His death for ours, atoning for our sins. This is only acceptable by faith in Christ. Belief without faith is no belief at all. The intellectual acceptance by a reasoning mind does not allow us to “enter into His rest”.
Romans 6:3 English Standard Version (ESV) Do you not know that all of us who have been baptized into Christ Jesus were baptized into his death?
Intellect cannot show you how to enter into His death. Only faith can lead you there. This partaking of the bread of life, the life, death, and resurrection can only happen by faith.
2 Peter 1:4 English Standard Version (ESV) by which he has granted to us his precious and very great promises, so that through them you may become partakers of the divine nature, having escaped from the corruption that is in the world because of sinful desire.
Intellect only wants to escape punishment. Faith desires to escape corruption by partaking in the divine nature which is only accessible by faith.
Hebrews 10:19-20 English Standard Version (ESV)
The Full Assurance of Faith
19 Therefore, brothers, since we have confidence to enter the holy places by the blood of Jesus, 20 by the new and living way that he opened for us through the curtain, that is, through his flesh,
This portion of Hebrews was entitled “The Full Assurance of Faith” to emphasize that the only assurances we have are by faith. Our intellect will not get us into the faith promises.
Isaiah 53:4 English Standard Version (ESV) Surely he has borne our griefs and carried our sorrows; yet we esteemed him stricken, smitten by God, and afflicted.
