Thanks. Love that song. I believe we really can be sure, can have absolute confidence, as Job did:
In Job 19:25, Job confidently states: “But as for me, I know that my Redeemer lives...”
Job wrote this approximately 2,000 years before Yeshua ha Meshiach rose from the dead.
Job foresaw that reality. For he went on to say, “And after my skin is destroyed, this I know, That in my flesh I shall see God, Whom I shall see for myself, And my eyes shall behold, and not another. How my heart yearns within me!” (Job 19:25, 26).
