True believers may have the assurance of their salvation in various ways shaken, diminished, and intermitted; as, by negligence in preserving of it; by falling into some special sin, which wounds the conscience, and grieves the Spirit; by some sudden or vehement temptation; by God's withdrawing the light of his countenance, and suffering even such as fear him to walk in darkness, and to have no light: So 5:2,3,6 Ps 51:8,12,14 Eph 4:30,31 Ps 77:1-10 Mt 26:69-72 Ps 31:22 Ps 88:1-18 Isa 1:10 yet are they never utterly destitute of that seed of God, and life of faith, that love of Christ and the brethren, that sincerity of heart and conscience of duty, out of which, by the operation of the Spirit, this assurance may in due time be revived, 1Jo 3:9 Lu 22:32 Job 13:15 Ps 73:15 Ps 51:8,12 Isa 1:10 and by the which, in the mean time, they are supported from utter despair.

Mic 7：7，8，9 Jer 32：40 Isa 54：7-10 Ps 22：1 Ps 88：1-18 4 ）真正的信徒可能保证他们的救恩，在以各种方式发生动摇，削弱和intermitted ；作为，疏忽，在维护它；由落入一些特殊的单，其中伤口的良知，并格雷乌斯精神；一些突发或强烈诱惑；上帝的撤回根据自己的国家进行，与苦难，甚至如怕他走在夜色中，并没有轻：那么5：2，3，6的PS 51：8，12，14弗4： 30，31常任77：1-10吨26：69-72聚苯乙烯31：22的PS 88：1-18伊萨1：10 ，但他们从来没有赤贫的种子神的，和生活的信心，而基督的爱和弟兄们，表示真诚的心灵和良知的税，其中，由行动的精神，这样的保证，可在适当时候恢复， 1jo 3时09卢22时32分就业13：15的PS聚苯乙烯73：15 51：8，12伊萨1：10 ，由其中，在平均时间，他们都支持从绝望。

The results showed polymeric diaryliodonium salts were effective aryl ion transfer reagents. Thirdly, a new type polymer supported hypervalent iodine reagents poly { [4-Hydroxy iodo] styrene} has been developed.
