After Jesus died and returned to heaven (the ascension), angels promised he would one-day return (Acts 1:11). This is anticipated as the “second coming” of Jesus to earth.
Key verse about Second Coming: Then the father realized that this was the exact time at which Jesus had said to him, “Your son will live.” So he and his whole household believed. (John 4:53-54, NIV).
A lifelong student of the Bible, Peter DeHaan, PhD, wrote the 1,000-page website ABibleADay.com to encourage people to explore the Bible. His main blog and many books urge Christians to push past the status quo and reconsider how they practice their faith in every area of their lives.
