Since it's a description of the atonement, it's a very central chapter of the Bible. Do your best to explain the whole, or just a part of Romans 5.
R5:1
Justified by Faith means, being found innocent and released from criminal charges by reason of our trust or reliance.
Peace with God means, YHWH would have been forced by His righteous character to punish with destruction creatures He loves, but since we have been Justified by Faith, He has no reason to destroy us.
Through Adoni Yahusha Meshiakh means, we trust & rely on Him as our Justifier. Specifically, believing that He took on Himself our crimes & resulting punishment and gave us His innocence & righteousness; rendering us innocent / justified.
R5:2
adds that Meshiakh not only gave us peace with YHWH, but even Grace, meaning undeserved help, loving assistance, Charity. And that our boast is in our hope of YHWH's glory, means we do not boast in our achievements or our ability, but in YWHW's astonishing charitable love, His suffering to save us, the outward expression (glory) of His inward beauty (character).
R5:3
We also Glory in our Sufferings which produces Perseverance, means we show His inner beauty (character) in us, by not allowing our suffering persecution to stop us from sharing His charitable offer of justification.
R5:4
Perseverance > Character > Hope, means the more stronger our will to continue to serve in the face of suffering, the more our selfishness will diminish & our selflessness (charitable love) will increase, which in turn produces more anticipation for YWHW's charitable love toward us and the one's we have shared His offer with.
