Romans 16:25-27

^A “is able” = dunamai. This is to be able, or something that is possible. It can also be empowered or being powerful. The Greek word for “miracle” (dunamis) comes from this root.
^B “strengthen” = sterizo. 13x in NT. From sterigx (a support, plant down); perhaps from histemi (to stand, place, set up, establish, stand firm). This is to make fast, support, strengthen, establish, fix firmly, to go resolutely.
^C “gospel” = euaggelion. From eu (well, good, rightly) + aggelos (angel, messenger; a messenger from God bringing news – whether a prophet or an angel); {from aggellos (to bring tidings); probably from ago (to bring, lead, carry, guide)}. This is literally “the good news,” used for the gospel. This is also where “evangelism” comes from.
^D “proclamation” = kerugma. 9x in NT. From kerusso (proclaim, preach, publish; properly, to act as a herald – announcing something publicly with confidence and/or to persuade). This is proclamation – both the preaching and that which is preached. Sometimes times used to refer to the Gospel itself.
^E “Jesus” = Iesous. From Hebrew Yehoshua (Joshua, the Lord is salvation); {from YHVH (proper name of the God of Israel; the self-existent and eternal one); {from havah (to become) or from hayah (to come to pass, become, be)} + yasha (to deliver, defend, help, preserve, rescue; properly, to be open, wide or free, which implies being safe. So, in a causative sense, this is to free someone). This is Jesus or Joshua in Greek – the Lord saves or the Lord is salvation.

This is uncovering, unveiling, appearing, manifestation, or revelation. This is where the word “apocalypse” comes from.
^H “mystery” = musterion. From mustes (an initiate); from mueo (to initiate someone into the secrets or mysteries of an order; to instruct learn, be disciples; properly, shutting your mouth and eyes to experience mystery); from muo (shutting eyes or mouth). This is a mystery or a secret doctrine that requires initiation to learn. In the New Testament, the plans of God were hidden until they were revealed in Christ through the Gospel. It is also used of Christian revelation in a broad sense rather than referring to something that cannot be known. This is the root of the word “mystery.”
^I “kept secret” = sigao. 10x in NT. From sige (silence, hush); perhaps from sizo (to hiss or hush). This is to be silent or hold peace.
^J “long” = aionios. From aion (an age, length of time). This is age-long, forever, everlasting. Properly, that which lasts for an age. This is where eon comes from.

^P “Gentiles” = ethnos. Probably from etho (a custom or culture). This is people who are united by having similar customs or culture. Generally, it is used to refer to Gentiles. This is a tribe, race, nation, or Gentiles in general. This is where the term “ethnicity” comes from.

^U “faith” = pistis. From peitho (to have confidence, urge, be persuaded, agree, assure, believe, have confidence, trust). This is less about knowing, believing, and repeating a list of doctrines then it is about trusting God. Faith means listening to God and seeking to live a holy life even (and especially) when we don’t understand how everything works or fits together. Faith is about being faithful (trusting and doing) rather than being all knowing.

^V “wise” = sophos. Related to saphes (clear). This is wise, clever, skilled, learned, cultivated. This is wisdom as expressed through a practical skill or ability as opposed to thoughtfulness, or intelligence.

So, this is opinion, honor, and dignity, but also praise, glory, renown, and worship.
