Heb 12:2-4,12-13, Phil 3:12-14, 1 Cor 9:24-27, 1 Tim 6:12
We have countless witnesses who tell us what faith is. Now, let's deeply believe that Jesus is the Christ and do our best for the world evangelization that God has entrusted to us.
Heb 12:1 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. 3 For consider him that endured such contradiction of sinners against himself, lest ye be wearied and faint in your minds. 4 Ye have not yet resisted unto blood, striving against sin. 12 Wherefore lift up the hands which hang down, and the feeble knees; 13 And make straight paths for your feet, lest that which is lame be turned out of the way; but let it rather be healed.
Phil 3:12 Not as though I had already attained, either were already perfect: but I follow after, if that I may apprehend that for which also I am apprehended of Christ Jesus. 13 Brethren, I count not myself to have apprehended: but this one thing I do, forgetting those things which are behind, and reaching forth unto those things which are before, 14 I press toward the mark for the prize of the high calling of God in Christ Jesus.
1 Cor 9:24 Know ye not that they which run in a race run all, but one receiveth the prize? So run, that ye may obtain. 25 And every man that striveth for the mastery is temperate in all things. Now they do it to obtain a corruptible crown; but we an incorruptible. 26 I therefore so run, not as uncertainly; so fight I, not as one that beateth the air: 27 But I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway.
1 Tim 6:12 Fight the good fight of faith, lay hold on eternal life, whereunto thou art also called, and hast professed a good profession before many witnesses.
