God gives a reason for us having hope. The hope that we have allows us to be men and women of God in the midst of trying times where we feel we might not want to give honour, or subdue to the temptation of flattery or worse, be afraid of someone. Even as our hope may be strong, we must remember to still be men and women of virtue, not chargeable with any open vice or profaneness, and sound in our faith. These things to do not justify us before God, but they give us our reputation around people.
The hope of the resurrection of the dead and eternal life can be found in the Old Testament ( Job 19:26-27 ) ( Isaiah 26:19 ) ( Daniel 12:2 ). Funny how the Jews had brought a prisoner to a Roman judge accusing him of a belief they all had.
And now I stand here on trial on account of my hope in the promise made by God to our ancestors, a promise that our twelve tribes hope to attain, as they earnestly worship day and night. It is for this hope, your Excellency, that I am accused by Jews! Why is it thought incredible by any of you that God raises the dead? – Acts 26:6-8
