12. Well, then, we have got thus far in the clearest light. You see that a religious, holy life, is every man's duty, not only as they owe it to God as their Creator, their Owner, Governor, and Benefactor; but also, because as lovers of ourselves, our reason commandeth us to have ten thousandfold more regard of a probable or possible joy and torment which are endless, than of any that is small and of short continuance. And if this be so, that a holy life is every man's duty, with respect to the life that is to come, then it is most evident, that there is such a life to come indeed, and that it is more than probable or possible, even certain. For if it be but man's duty to manage this life, by the hopes and fears of another life, men it must follow, that either there is such a life to come, or else that God hath made it man's duty to hope, and fear, and care, and labour, and live in vain: and that he himself doth tantalize and cheat his creatures, and rule the world by motives of deceit, and make religion and obedience to our Maker to be a life of folly, delusion, and our loss. And he that believeth this of God, doth scarce believe him to be God. Though I have mentioned this argument in another treatise, I think it not unmeet here to repeat it for thy benefit.
[Sidenote: That all the matters of this transitory life are to be estimated as they refer to the life to come.]
13. And seeing I suppose thee to be convinced of the life to come, and that man's happiness and misery is there, I must needs suppose that thou dost confess, that all things in this life, whether prosperity or adversity, honour or dishonour, are to be esteemed and used as they refer to the life to come. For nothing is more plain, than that the means are to have all their esteem and use in order to their end. That only is good in this life, which tendeth to the happiness of our endless life; and that is evil indeed in this life, that tendeth to our endless hurt, and to deprive us of the everlasting good. And therefore no price or motive should hire us to sin against God, and to forfeit or hinder our endless happiness.
[Sidenote: That no man can love God too much, nor make too sure of his salvation.]
14. I may suppose, if thou have reason, that thou wilt confess that God cannot be too much loved, nor obeyed too exactly, nor served too diligently (especially by such backward sinners, that have scarce any mind to love or worship him at all); and that no man can make too sure of heaven, or pay too dear for it, or do too much for his salvation, if it be but that which God hath appointed him to do. And that you have nothing else that is so much worth your time, and love, and care, and labour. And therefore though you have need to be stopped in your love, and care, and labour for the world, because for it you may easily pay too dear, and do too much; yet there is no need of stopping men in their love, and care, and labour for God and their salvation; which is worth more than ever we can do, and where the best are apt to do too little.
[Sidenote: That this life is given us for trial and preparation to the life to come.]
15. I also suppose thee to be one that knowest, that this present life is given us on trial,[14] to prepare for the life that shall come after; and that as men live here, they shall speed for ever; and that time cannot be recalled when it is gone, and therefore that we should make the best of it while we have it.
[Sidenote: That man's thoughts should be serious and frequent about his future state.]
16. I suppose thee also to be easily convinced, that seeing man hath his reason and life for matters of everlasting consequence, his thoughts of them should be frequent and very serious, and his reason should be used about these things, by retired, sober deliberation.
[Sidenote: That you can tell, or may do, which way your hearts and diligence are bent, whether most for this life, or for that to come.]
17. And I suppose thee to be a man, and therefore so far acquainted with thyself, as that thou mayst know, if thou wilt, whether thy heart and life do answer thy convictions, and whether they are more for heaven or earth; and therefore that thou art capable of self-judging in this case.
Perhaps you will say, that while I am directing you to be holy, I suppose you to be holy first; for all this seemeth to go far towards it. But I must profess that I see not any thing in all these suppositions, but what I may suppose to be in a heathen; and that I think all this is but supposing thee to have the use of thy reason, in the points in hand. Speak freely: Is there any one of all these points that thou canst or darest deny? I think there is not. And therefore if heathens and wicked men deny them in their practice, that doth but show that sin doth brutify them, and that, as men asleep, or in a crowd of business, they have not the use of the reason which they possess, in the matters which their minds are turned from.
