6. The infirmities also of our souls in duty, are oftentimes a great discouragement to us, in our approaches to the most holy, jealous God. To find so little knowledge of God, so little love to him, such cold desires, such wandering and distracted thoughts, such dull requests: it is hard to have lively and thankful apprehensions of God's acceptance of such defective, lame meditations or prayers; but we are apt to think that he will abhor both them and us, and that he can take no pleasure in them, yea, that it is as good not pray at all. Here faith hath full relief in Christ: two things it can say from him to encourage the fearful soul: (1.) That our acceptance with the Father is through the merits of his Son; and he is worthy, though we are unworthy. If we have but the worthiness of faith, and repentance, and sincere desire, Christ hath the worthiness of perfect holiness and obedience for us. We go not to the Father in our own names, but in his; and whatever we ask the Father in the name of Christ according to his will, he will give it us, John xvi. 23; xiv. 13; xv. 16. (2.) That all the infirmities of our souls and services are forgiven us through Christ: he hath undertaken to answer for them all, and to justify us from all such accusations. By faith thou mayst, as it were, hear Christ thus speaking for thine encouragement: Go boldly, poor sinner, into my Father's presence: fear not the guilt of thy sins, nor the imperfection of thy prayers; as long as thou truly repentest of them, and desirest to be delivered from them, and trustest in me, I am thy worthiness; my righteousness is perfect without spot; I have taken all thy faults and failings upon me; I have undertaken to answer for all the imperfections of thy holy things: sincerity is thy endowment; perfection is mine: trust me in the performance of the trust which I have undertaken.
