“while we do not look at the things which are seen, but at the things which are not seen. For the things which are seen are temporary, but the things which are not seen are eternal.”
II Corinthians 4:18 NKJV
https://bible.com/bible/114/2co.4.18.NKJV
“Heaven with its attractions is before you, an eternal weight of glory, which you may lose or gain. Which shall it be? Your life and your character will testify the choice you have made. I feel the more anxious because I see so many indifferent upon the subjects of infinite importance. They are always busy here and there about matters of minor importance, and the one great subject is put out of their thoughts. They have no time to pray, no time to watch, no time to search the Scriptures. They are altogether too busy to make the necessary preparation for the future life. They cannot devote time to perfect Christian characters and in diligence to secure a title to heaven.
If you have life eternal, you must be earnest and work to the point… Glorify God by choosing His way, His will. He will be your wise counselor and your fast, unchanging Friend. “
(Our High Calling 44.4, 5)
