To human agencies is committed the work of extending the triumphs of the cross from point to point. As the Head of the church, Christ is authoritatively calling upon everyone who claims to believe on Him to follow His example of self-denial and self-sacrifice in working for the conversion of those whom Satan and his vast army are exerting every power to destroy. God's people are called upon to rally without delay under the bloodstained banner of Christ Jesus. Unceasingly they are to continue their warfare against the enemy, pressing the battle even to the gates. And everyone who is added to the ranks by conversion is to be assigned his post of duty. Everyone should be willing to be or to do anything in this warfare. When church members put forth earnest efforts to advance the message, they will live in the joy of the Lord and will meet with success. Triumph always follows decided effort. 7T 30.1
