10. _We have had our conversation in the world_; even in the world of the ungodly: not only among the children of God (that were, comparatively, a little thing:) but among the children of the devil, among those that _lie in wickedness_, ἐν τῷ πονηρῷ, _in the wicked one_. * What a world is this! How throughly impregnated with the spirit it continually breathes! As our God is good and doth good, so the God of this world, and all his children, are evil, and do evil, (so far as they are suffered) to all the children of God. Like their father, they are always lying in wait, or _walking about, seeking whom they may devour_: using fraud or force, secret wiles or open violence, to destroy those who are not of the world: continually warring against our souls, and by old or new weapons and devices of every kind, labouring to bring them back into the snare of the devil, into the broad road that leadeth to destruction. 11. _We have had our_ whole _conversation in_ such _a world, in simplicity and godly sincerity_. First, _in simplicity_. This is what our Lord recommends, under the name of a _single eye. The light of the body_, saith he, _is the eye. If therefore thine eye be single, thy whole body shall be full of light._ The meaning whereof is this. What the eye is to the body, that the intention is, to all the words and actions. If therefore this eye of thy soul be single, all thy actions and conversation, shall be _full of light_, of the light of heaven; of love and peace and joy in the Holy Ghost. We are then simple of heart, when the eye of our mind is singly fixt on God: when in all things we aim at God alone, as our God, our portion, our strength, our happiness, our exceeding great reward, our all, in time and eternity. This is simplicity; when a steddy view, a single intention of promoting his glory, of doing and suffering his blessed will, runs thro’ our whole soul, fills all our heart, and is the constant spring of all our thoughts, desires and purposes.
