Shalom!

Peace, first of all, is granted by God, and secondly, as a reward for obedience (Lev 26:3, 6).

There’s no peace -only fear of punishment- for the disobedient because of the lack of the intimate presence of God, who is love (Hab 1:13; 1 Jn 4:18). But for those who have either obeyed or truly repented for their disobedience, we’ve been freed from the yoke of slavery to sin (which results in death) and we’re ‘enabled to walk with heads held high’ to serve our Lord unhindered (Lev 26:13; Ro 6:23; Gal 5:1, 13).  

Throughout the Old Testament there’s an ebb and flow of the people of Israel enjoying peace and prosperity because of their obedience to God (and often His leaders), and suffering from death, lack, and destruction because of their disobedience (from Judges to 2 Chronicles; Jn 10:10). (Remember:  Although the Lord is merciful and long-suffering, there’ll be a Day of Judgment for all of us where we’re given the wages of all that we’ve done on earth, whether good or bad [2 Pe 3:9; 2 Co 5:10; Ac 3:19].)  

‘May the God of hope fill you with all joy and peace as you trust in him, so that you may overflow with hope by the power of the Holy Spirit’ (Ro 15:13).
