James 4:8

Draw nigh to God, and he will draw nigh to you
This must be understood consistently with the perfection of God's immensity and omnipresence: the saints draw nigh to God when they present their bodies in his sanctuary; when they tread in his courts, and attend his ordinances; where they always find it good for them to draw nigh unto him; and blessed is the man that approaches to him in faith and fear: they draw nigh to him when they come to the throne of his grace, for grace and mercy to help them; when they draw near to him in prayer with true hearts, and lift them up with their hands to God; when in the exercise of faith and hope they enter within the vail, and come up even to his seat; and lay hold on him as their covenant God and Father; and he draws nigh to them by granting them his gracious presence, by communicating his love to them, by applying the blessings of his grace, by helping them in times of need and distress, and by protecting them from their enemies; the contrary to which is expressed by standing afar off from them. Now this is not to be understood as if men could first draw nigh to God, before he draws nigh to them; for as God first loves, so he first moves; he takes the first step, and, in conversion, turns and draws men to himself; though this does not respect first conversion, but after acts in consequence of it; nor is it to be considered as a condition of the grace and favour of God, in drawing nigh to his people, but is expressive of what is their duty, and an encouragement to it:

cleanse [your] hands, ye sinners, and purify [your] hearts, ye
double minded;
the persons addressed are not the profane men of the world, but sinners in Zion, formal professors, hypocritical persons; who speak with a double tongue to men, and who draw nigh to God with their mouths, but not with their hearts; who halt between two opinions, and are unstable in all their ways: cleansing of their hands and hearts denotes the purity of outward conversation, and of the inward affections; and supposes impurity both of flesh and spirit, that the body and all its members, the soul and all its powers and faculties, are unclean; and yet not that men have a power to cleanse themselves, either from the filth of an external conversation, or from inward pollution of the heart; though a man attempts the one, he fails in it; and who can say he has done the other? ( Job 9:30 Job 9:31 ) ( Proverbs 20:9 ) . This is not to be done by ceremonial ablutions, moral services, or evangelical ordinances; this is God's work only, as appears from his promises to cleanse his people from their sins, by sprinkling clean water upon them; from the end of Christ's shedding his blood, and the efficacy of it; and from the prayers of the saints, that God would wash them thoroughly from their iniquity, and cleanse them from their sin, and create clean hearts in them: and yet such exhortations are not in vain, since they may be useful to convince men of their pollution, who are pure in their own eyes, as these hypocritical, nominal professors, might be; and to bring them to a sense of their inability to cleanse themselves, and of the necessity of being cleansed elsewhere; and to lead them to inquire after the proper means of cleansing, and so to the fountain of Christ's blood, which only cleanses from all sin.
