Is Christ’s return imminent in light of current world events?

In light of ongoing global events—such as wars (e.g., the conflict involving Russia), geopolitical instability, and widespread moral and social upheaval—many Christians interpret these as signs that the “end times” are approaching. My questions are twofold: Imminence of Christ’s return: Within mainstream Christian theology, do these kinds of events meaningfully support the belief that Christ’s return is near? How have passages such as Matthew 24; Luke 21; 1 Thessalonians 5:1–6; and Revelation 6–16 traditionally been understood in relation to historical events versus recurring patterns throughout history? Christ’s presence before the Parousia: Is there any biblical basis for the idea that Christ is presently “walking the earth” prior to His return, possibly until all believe in Him as the Christ? How do texts like Matthew 28:20 (“I am with you always”), John 14–16 (the coming of the Holy Spirit), Acts 1:9–11, and Revelation 1:12–18 inform orthodox interpretations of Christ’s presence now versus His future, visible return? I am seeking answers grounded in Scripture and recognized Christian interpretive traditions (e.g., patristic, Catholic, Orthodox, or Protestant), rather than speculative or purely contemporary prophetic claims.
