This passage includes two difficult statements--verse 30, "Truly I say to you, this generation will not pass away until all these things take place." And verse 32, "But of that day or hour no one knows, not even the angels in heaven, nor the Son, but the Father alone." You will love the answers that come out of the context, and from the incarnation--both are treasured truths and apply to us today, and speak to being prepared (to LIVE and to DIE), and ready for the return of Christ.
