Eternity is not “a long time” but the “absence of time”. All that God has destined for you has been planned out in heaven.
Surely You have granted me eternal blessings and made me glad with the joy of Your presence (Psalm 21:6). God… called you to His eternal glory (1 Pet 5:10), for the gift of God is eternal life in Christ Jesus (Romans 6:23). He has set eternity in the hearts of men (Ecclesiastes 3:11).
Remember God is eternal and that He operates in an eternal time frame. You are neither eternal nor divine, but you are eternally united to Christ’s divinity. Praise Him for that.
