Let Richard Sibbes (1577-1635) encourage you, here are some quotes from his work, The Bruised Reed.
But if we have this for a foundation truth, that there is more mercy in Christ than sin in us, there can be no danger in thorough dealing (with sin). (pgs. 12-13)
A holy despair in ourselves is the ground of true hope. (pg. 14)
Let us not therefore be discouraged at the small beginnings of grace, but look on ourselves as elected to be ‘holy without blame’ (Eph. 1:4). Let us look on our imperfect beginning only to enforce further striving to perfection, and to keep us in a low opinion of ourselves. Otherwise, in case of discouragement, we must consider ourselves as Christ does, who looks on us as those he intends to fit for himself. Christ values us by what we shall be…We call a little plant a tree, because it is growing to be so. (pg. 17)
It would be a good contest amongst Christians, one to labour to give no offence, and the other to labour to take none. The best men are severe to themselves, tender over others. (pg. 23)
Sometimes a Christian has such confused thoughts that he can say nothing but, as a child, cries, ‘O Father’, not able to express what he needs, like Moses at the Red Sea. These stirrings of the spirit touch the heart of God and melt him into compassion towards us, when they come from the Spirit of adoption, and from a striving to be better. (pgs. 50-51)
