_Reason_ 1. Because, as in all things that are of any moment, there is alwayes required some preparing of the subject, for example, as in husbandry, plowing and harrowing of the ground: so and much more also is it required that we should prepare our hearts to receive the word of God with benefit, _Ieremiah 4.3,4._ Now there can be no fitter preparation, then by sincerity to lay aside all those things, that are contrary to the word, and hinder the efficacy thereof. 2. Because the word of God is sincere, and therefore it requires sincerity in those that receive it, _1 Epistle_ chapter 2. verse 2. 3. Because without sincerity nothing at all is done aright. For sincerity is the common affection of obedience. _Vse_ 1. This may serve to reprove those, that have no care at all, rightly to dispose themselves for to receive the word of God aright. 2. To exhort us, to labour chiefly for this purity of minde, and sincerity of heart. Doctrine 2. _They that have a pure minde, do willingly receive and retain those things that are proposed unto them out of the Prophets and Apostles._ This is gathered from verse 2. _Reason_ 1. Because Christs sheepe know his voice and follow him, _Iohn 10.27._ Now his voice sounds in the Prophets and Apostles. 2. Because in the Prophets and Apostles all things agree with sincerity, _1 Peter 2.2._ _Psalms 19.8,9._ _Vse._ This may serve to informe us, to examine our minds according to this rule: for they that care not for the words of the Prophets and Apostles, have not purity of minde; but they that cleave fast unto them, although it be accompanied with divers infirmities, have alwayes in readinesse a sure argument of their sincerity. Doctrine 3. _Yet the very best have need to be often stirred up unto these duties._ This is gathered from these words; _This second Epistle I now write._ So _Philippians 3.1_, and this Epistle, chapter 1. verse 10,13. Doctrine 4. _Such admonitions are works of Christian charity._ This is gathered from this title, _beloved_. _Reason_ 1. Because they tend to deliver men from the greatest evill, and to communicate unto them the greatest good. 2. Because they pertaine unto the communication which is exercised by charity. _Use_ 1. This may serve to reprove those that cannot endure admonitions, and take them for their enemies that use them. _Galatians 4.16._ _2 Timothy 4.3._ 2. To exhort us, to exercise our selves unto this duty with all charity. * * * * * Verse 3. _Knowing this first, that there shall come in the last dayes, scoffers, walking after their own lusts,_ Verse 4. _And saying, Where is the promise of his comming?
