Ephesians 1:9-10

He made known to us the mystery of His will according to His good pleasure, which He purposed in Christ, with regard to the fulfillment of the times (that is, the end of history, the climax of the ages) to bring all things together in Christ, things in the heavens and things on the earth.

We are coming to an end of an age, and God will bring all things together in Christ. God hasn’t kept His people in the dark about His return to the earth.   Jesus will return for His church and chosen people who believe in Him. The believer should be keeping themselves ready for His return with a faithful focus on God and His word.
