To Matthew in his wealth, and to Andrew and Peter in their poverty, the same test was brought; the same consecration was made by each. At the moment of success, when the nets were filled with fish, and the impulses of the old life were strongest, Jesus asked the disciples at the sea to leave all for the work of the gospel. So every soul is tested as to whether the desire for temporal good or for fellowship with Christ is strongest. CS 216.1
Principle is always exacting. No man can succeed in the service of God unless his whole heart is in the work, and he counts all things but loss for the excellency of the knowledge of Christ. No man who makes any reserve can be the disciple of Christ, much less can be His colaborer. When men appreciate the great salvation, the self-sacrifice seen in Christ's life will be seen in theirs. Wherever He leads the way, they will rejoice to follow.—The Desire of Ages, 273. CS 216.2
