The Lord has a great work to be done, and He will bequeath the most in the future life to those who do the most faithful, willing service in the present life. The Lord chooses His own agents, and each day under different circumstances He gives them a trial in His plan of operation. In each true-hearted endeavor to work out His plan, He chooses His agents not because they are perfect but because, through a connection with Him, they may gain perfection.
God will accept only those who are determined to aim high. He places every human agent under obligation to do his best. Moral perfection is required of all. Never should we lower the standard of righteousness in order to accommodate inherited or cultivated tendencies to wrong-doing. We need to understand that imperfection of character is sin. All righteous attributes of character dwell in God as a perfect, harmonious whole, and every one who receives Christ as a personal Saviour is privileged to possess these attributes.
