Charles H. Spurgeon on Psalms 51:11

Cast me not away from thy presence. Throw me not away as worthless; banish me not, like Cain, from thy face and favour. Permit me to sit among those who share thy love, though I only be suffered to keep the door. I deserve to be forever denied admission to thy courts; but, O good Lord, permit me still the privilege which is dear as life itself to me. Take not thy Holy Spirit from me. Withdraw not his comforts, counsels, assistances, quickenings, else I am indeed as a dead man. Do not leave me as thou didst Saul, when neither by Urim, nor by prophet, nor by dream, thou wouldst answer him. Thy Spirit is my wisdom, leave me not to my folly; he is my strength, O desert me not to my own weakness. Drive me not away from thee, neither do thou go away from me. Keep up the union between us, which is my only hope of salvation. It will be a great wonder if so pure a spirit deigns to stay in so base a heart as mine; but then, Lord, it is all wonder together, therefore do this, for thy mercy's sake, I earnestly entreat thee.
