Psalms 51:11

Casting away from God’s presence implies a rejection as God’s servant. Saul had suffered such a fate for his continuing rebellion against Yahweh. In Old Testament times God gave His Holy Spirit selectively (to empower only some believers) and temporarily (primarily to empower them for special acts of service). Since the Day of Pentecost all believers enjoy the permanent indwelling of the Holy Spirit in the Church Age (John 14:17; Romans 8:9). Consequently the possibility of God withdrawing His Spirit from David was a real one for him, but it is not for us. [Note: For further study of the ministry of the Holy Spirit in Old Testament times, see Walvoord, pp. 71-73; L. S. Chafer, Systematic Theology, 6:66-79; or Leon Wood, The Holy Spirit in the Old Testament.] It is possible that a Christian may lose his or her opportunities to serve the Lord, however (1 Corinthians 9:27). For example, a Christian who gets involved in gross sin will not lose his or her salvation (John 10:28-29), but he or she may lose the opportunity to serve God in a leadership capacity (cf. 1 Corinthians 9:27).
