Isa 50:7-9

7 For the Lord GOD will help me; therefore shall I not be confounded: therefore have I set my face like a flint, and I know that I shall not be ashamed.

8 [He is] near that justifieth me; who will contend with me? let us stand together: who [is] mine adversary? let him come near to me.

9 Behold, the Lord GOD will help me; who [is] he [that] shall condemn me? lo, they all shall wax old as a garment; the moth shall eat them up.

Heb 12:1-2

1 Wherefore seeing we also are compassed about with so great a cloud of witnesses, let us lay aside every weight, and the sin which doth so easily beset [us], and let us run with patience the race that is set before us,

2 Looking unto Jesus the author and finisher of [our] faith; who for the joy that was set before him endured the cross, despising the shame, and is set down at the right hand of the throne of God.

Matt 24:13-14

13 But he that shall endure unto the end, the same shall be saved.

14 And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come.
