We are sojourners and pilgrims (1Pe 2:9-11) - aliens in this life. Psalm 16 has the following elements: a prayer for watch-care, the expression of total dependence, a declaration of devotion, thankful contentment, a firm assurance, and a blessed hope. Seven conditions of a pilgrim: (1) There's a sense of constant threat as opposed to refuge - casah (Psa 16:1, 2Co 4:4). We live in a battlefield (Eph 6:12). (2) There's necessity for spiritual adjustment (Psa 16:2-3). Apart from Jesus Christ, we are the same old sinners (Rom 7:18). Love exalts others above self (Psa 16:3, Jam 1:17, Phi 2:3). Only spiritual growth and fellowship can keep us grace oriented. (3) Pilgrim life is progressive sanctification (Psa 16:4-5, 2Pe 1:2). Idol worshipers are a contrast (Jer 2:11, Rom 1:23). We are sanctified progressively through spiritual growth and practical application (Joh 17:17, Rom 12:1-2, 1Th 4:3). (4) A thankful contentment is difficult; it's easy to complain (Psa 16:5-6, Psa 23:5). We cannot lose what God has provided in Grace (Rom 11:29). (5) Stability in times of trial (Psa 16:7-8). David makes a commitment praise the Lord no matter what his lot may be (Psa 16:7). (6) We can pass through this world with hope - Hebrew batach (Psa 16:9, Phi 4:4, Job 19:25-26). (7) Anticipation or expectation of entering heaven (Psa 16:10-11). " Holy One" is applied to the Messiah Jesus Christ (Act 2:24-32). "In Your presence is fullness of joy...(Psa 37:4).
