2 Tim 1:8, 2 Tim 4:5, 1 Cor 9:7, 1 Cor 9:9-10,23-25
At that time, when the saints preached that Jesus was the Christ, they were persecuted by the Jews. Paul told Timothy to continue preaching the gospel even in the midst of suffering. (2 Tim 2:3-5, 2 Tim 4:5)
2 Tim 2:3 Thou therefore endure hardness, as a good soldier of Jesus Christ. 4 No man that warreth entangleth himself with the affairs of this life; that he may please him who hath chosen him to be a soldier. 5 And if a man also strive for masteries, yet is he not crowned, except he strive lawfully.
2 Tim 4:5 But watch thou in all things, endure afflictions, do the work of an evangelist, make full proof of thy ministry.
God supplies the needs of those who preach the gospel. (2 Tim 2:6, 1 Cor 9:7, 9-10)
2 Tim 2:6 The husbandman that laboureth must be first partaker of the fruits.
1 Cor 9:7 Who goeth a warfare any time at his own charges? who planteth a vineyard, and eateth not of the fruit thereof? or who feedeth a flock, and eateth not of the milk of the flock? 9 For it is written in the law of Moses, thou shalt not muzzle the mouth of the ox that treadeth out the corn. Doth God take care for oxen? 10 Or saith he it altogether for our sakes? For our sakes, no doubt, this is written: that he that ploweth should plow in hope; and that he that thresheth in hope should be partaker of his hope.
We must do our best to spread the gospel. (1 Cor 9:23-25)
1 Cor 9:23 And this I do for the gospel's sake, that I might be partaker thereof with you. 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.
