24 Only fear the Lord, and serve him in truth with all your heart: for consider how great things he hath done for you.
58 Therefore, my beloved brethren, be ye stedfast, unmoveable, always abounding in the work of the Lord, forasmuch as ye know that your labour is not in vain in the Lord.
9 And let us not be weary in well doing: for in due season we shall reap, if we faint not.
