“[…] We are coming off completely victorious through the one who loved us. For I am convinced that neither death nor life nor angels nor governments nor things now here nor things to come nor powers nor height nor depth nor any other creation will be able to separate us from God’s love that is in Christ Jesus our Lord.”
~Rom. 8:37-39

This was my favorite Scripture as a teenager. I am happy to say it still rings true.
When the Apostle Paul was introducing this verse, he quoted Psalm 44, written by the three loyal sons of the rebellious Korah when they were evidently undergoing tremendous stress.
Assir, Elkanah, and Abiasaph did not join their father’s rebellion against Moses in the desert, and instead retained the privilege of continuing to serve Jehovah as priests. (Num. 26:10,11; 1 Chro. 26:19; 2 Chro. 20:18,19)
Sometimes life’s trials, either major or minor, may have us doubting whether we deserve God’s love or if eternal life is all it’s cut out to be.
In order to endure joyfully we need this conviction that is the foundation of our faith.
We need to be convinced that if we adopt a Christian attitude, we can battle our demons and ‘conquer the world.’ (John 16:33)
God promises that no creation- not even ourselves- can separate us from his love.
