"Blessed shalt thou be when thou comest in, and blessed shalt thou be when thou goest out" (Deuteronomy 28:6).
Just before entering the Promised Land, God gave the children of Israel two choices: they could either be greatly blessed (Deuteronomy 28:1-14) or be greatly cursed (28:15-68). The blessings would come only if they obeyed (28:12); the cursings would come if they disobeyed (28:15).
One of God's promised blessings of obedience rested upon one's private homelife, "when thou comest in, and . . . when thou goest out" (28:6). God, who created Adam and Eve, the first family, and united them in one flesh, established the home and loves to bless that home where God is the Lord. David said, "I will behave myself wisely in a perfect way.
. . . I will walk within my house with a perfect heart" (Psalm 101:2).
God also desires to give enablement to do His will. When God appeared to Solomon and said, "Ask what I shall give thee" (I Kings 3:5), the young king responded, "And now, O Lord my God . . . I am but a little child: I know not how to go out or come in" (v.7); that is, "I don't know how to begin or finish." He therefore asked for wisdom and received it. God's promise to present day believers is the same, "If any of you lack wisdom, let him ask of God, that giveth to all men liberally, and upbraideth not; and it shall be given him" (James 1:5).
Then there is the promise of preservation throughout one's lifetime of service. "The Lord shall preserve thy going out and thy coming in from this time forth, and even for evermore" (Psalm 121:8). "He shall preserve thy soul" (Psalm 121:7). Soul preservation not only extends through our earthly life but "even forever more." "Praise God from Whom all blessings flow." NPS
