Without the certainty of His resurrection, we would come to the end of this life without hope, with nothing to anticipate except despair and doubt. But because He lives, we rejoice, knowing soon we will meet our Savior face to face, and the troubles and trials of this world will be behind us.
From John 16:31-33: “Jesus answered them, ‘Do you now believe? The hour is coming, indeed it has come, when you will be scattered, each one to his home, and you will leave me alone. Yet I am not alone because the Father is with me. I have said this to you, so that in me you may have peace. In the world you face persecution. But take courage; I have conquered the world!'”
