God's Proving^{*1859, Testimonies for the Church 1:186-190 (The Laodicean Church).}

God will prove His people. Jesus bears patiently with them, and does not spew them out of His mouth in a moment. Said the angel: “God is weighing His people.” If the message had been of as short duration as many of us supposed, there would have been no time for them to develop character. Many moved from feeling, not from principle and faith, and this solemn, fearful message stirred them. It wrought upon their feelings, and excited their fears, but did not accomplish the work which God designed that it should. God reads the heart. Lest His people should be deceived in regard to themselves, He gives them time for the excitement to wear off, and then proves them to see if they will obey the counsel of the True Witness.1TT 64.1

God leads His people on, step by step. He brings them up to different points calculated to manifest what is in the heart. Some endure at one point, but fall off at the next. At every advanced point the heart is tested and tried a little closer. If the professed people of God find their hearts opposed to this straight work, it should convince them that they have a work to do to overcome, if they would not be spewed out of the mouth of the Lord.1TT 64.2

Said the angel: “God will bring His work closer and closer to test and prove every one of His people.” Some are willing to receive one point; but God brings them to another testing point, they shrink from it and stand back, because they find that it strikes directly at some cherished idol. Here they have opportunity to see what is in their hearts that shuts out Jesus. They prize something higher than the truth, and their hearts are not prepared to receive Jesus. Individuals are tested and proved a length of time to see if they will sacrifice their idols and heed the counsel of the True Witness. If any will not be purified through obeying the truth, and overcome their selfishness, their pride, and evil passions, the angels of God have the charge: “They are joined to their idols, let them alone,” and they pass on to their work, leaving these with their sinful traits unsubdued, to the control of evil angels. Those who come up to every point, and stand every test, and overcome, be the price what it may, have heeded the counsel of the True Witness, and they will receive the latter rain, and thus be fitted for translation. ...1TT 64.3

Oh, that every lukewarm professor could realize the clean work that God is about to make among His professed people! Dear friends, do not deceive yourselves concerning your condition. You cannot deceive God. Says the True Witness: “I know thy works.” The third angel is leading up a people, step by step, higher and higher. At every step they will be tested.1TT 65.1
