The most straightforward and simple statement of Fanny J. Crosby’s “Blessed Assurance” is Paul’s statement to the church at Rome:
31 What (tis) then (oun) shall we say (legō) in response to (pros) these (houtos) things? If (ei ·ho) God (theos) is for (hyper) us (hēmeis,) who (tis) can be against (kata) us (hēmeis?) 32 He (pheidomai) who (hos) did (pheidomai) not (ou) spare (pheidomai·ho) his (idios) own Son (hyios,) but (alla) delivered (paradidōmi) him (autos) up (paradidōmi) for (hyper) us (hēmeis) all (pas,) how (pōs) will he (charizomai) not (ouchi) also (kai,) along with (syn) him (autos,) graciously give (charizomai) us (hēmeis ·ho) all (pas) things? 33 Who (tis) will bring a charge (enkaleō) against (kata) God’s (theos) elect (eklektos?) It is God (theos) who (ho) justifies (dikaioō).
And if there is any doubt, look at Paul’s delineation of “these things.” The things that he (and we) are responding to are:
1) The glorious freedom of the children of God
2) Our adoption into the family of God as His children
3) The Holy Spirit helping us in our weaknesses and interceding for us, knowing God’s will for us
4) God using all things together for our good, so that we are conformed to the image of our Creator
5) Finally our predestination, calling, justification and ultimate glorification
Not for judgment — God the Father does not send Jesus His Son into the world for judgment purposes. In fact, that’s completely unnecessary for the world stands condemned already; judgment has been conferred; we are all doomed.
I am convinced if we start with this undeniable truth — that Jesus is a Savior and not a Judge, we might understand the level of His commitment to His Father’s purposes.
“For God sent not his Son into the world, that he judge the world, but that the world be saved by him.”
Jesus comes to earth to save, not to condemn. He comes to seek and save what is lost.
Jesus promises that His sheep listen to His voice and follow after Him because He knows them. He says that he “gives them eternal life and they never perish; no one [is able to] snatch them from [His] care.” God the Father who is “greater than all” gives Jesus the sheep “and no one can snatch them out of the Father’s care.” Then Jesus reminds us that He and His Father are One.
Jesus tells the Jews to believe Him because His deeds show that the Father is in Him and He is in the Father. (John 10:37-38) The author of Hebrews tells us that “faith gives substance to our hopes, and makes us certain of realities we do not see.” (Hebrews 11:1)
Our reality is that our salvation is secure — God is more powerful than anything in the universe, and He is able to sustain us. Paul writes that he is convinced that “nothing in death or life, in the realm of spirits or superhuman powers, in the world as it is or the world as it shall be, in the forces of the universe, in heights or depths — nothing in all creation can separate us from the love of God in Christ Jesus our Lord.” (Romans 8:38-39)
Jesus promises the same blessed assurance. Therefore, the hymn: “This is my story; this is my song — praising my Savior all the day long. Blessed assurance, Jesus is mine. Oh, what a foretaste of glory divine. Born of His Spirit, washed in His blood. This is my story; this is my song!”
