1 Timothy / Question
Paul describes God as the one who alone has immortality and who dwells in unapproachable light. He adds that no one has ever seen him or can see him. See 1 Timothy 6:15–16.
In 1 Timothy 6:15–16, the writer bursts into praise while speaking about God’s coming “showing” at the right time. God is described as uniquely supreme: the only ruler, above every other authority. These lines close a stretch where Timothy is urged to pursue integrity and keep the command “without stain” until the appearing of Jesus Christ (immediately before, 1 Timothy 6:14).
These verses function as a short praise section tied to the “appearing” just mentioned (the public “showing” of Jesus Christ).
A careful answer keeps the immediate passage, the book's argument, and the whole-Bible storyline together, so the question is answered in context instead of as a detached idea.
Start with 1 Timothy 6:15-16, then read the surrounding section so the answer stays connected to the passage's flow.
15which in its own times he will show, who is the blessed and only Ruler, the King of kings, and Lord of lords;
16who alone has immortality, dwelling in unapproachable light; whom no man has seen, nor can see: to whom be honor and eternal power. Amen.
