I have read this passage a number of times in different devotionals.
There is always one thing that is left out, that is missing in many of the discussions on this verse:
This event took place under the Old Covenant, under the blood of bulls and goats which could never cleanse sin, but which could atone for sin until the fullness of time would come (Galatians 4:47).
Jesus is the Perfect Sacrifice, the propitiation for all the sins of the world (1 John 2:1-2)
We are not under an Old Covenant, but under the New Covenant.
He is our God, and we are His people. We do not seek great things for ourselves, that is certainly true, because ... He is already blessed us with all spiritual blessings in Christ Jesus (Ephesians 1:6)
The name of the scribe whom Jeremiah is speaking to, Baruch, is taking down a prophecy for Jeremiah.
Baruch was really hard up at this point in the history of the nation of Israel:
"Thou didst say, Woe is me now! for the LORD hath added grief to my sorrow; I fainted in my sighing, and I find no rest." (Jeremiah 45:3)
Baruch had every reason to feel down. Israel was beseiged by the Babylonians. Those who were still alive were going to be taken captive to Babylon very soon. The city of Jerusalem was going to be burned to the ground, and the Temple was going to be destroyed.
Yet God promised Baruch that his life would given to him as "spoils" wherever he went.
Today, in Christ Jesus, we are more than mere spoils.
We have been redeemed from sin and death!
"Christ hath redeemed us from the curse of the law, being made a curse for us: for it is written, Cursed is every one that hangeth on a tree:" (Galatians 3:13)
And in Christ Jesus, we are not just barely getting by!
"31What shall we then say to these things? If God be for us, who can be against us? 32He that spared not his own Son, but delivered him up for us all, how shall he not with him also freely give us all things." (Romans 8:31-32)
In fact, we are called to reign in life with Him (Romans 5:17)
Let us also never forget the promises which Christ Jesus has fulfilled for us through the Cross:
"14In righteousness shalt thou be established: thou shalt be far from oppression; for thou shalt not fear: and from terror; for it shall not come near thee." (Isaiah 54:14)
We have His righteousness today. In fact, we are made the righteousness of God in Christ Jesus! (2 Corinthians 5:21).
Baruch received comfort that he would receive his life as "a prey." In Christ Jesus, we receive life and that more abundantly (John 10:10) and eternal life (John 3:16).
Indeed, we receive our life as more than a prey, because of Jesus!
