In Psalm 138:8 David declares confidently that God’s purposes for him will come to pass: “The LORD will fulfill His purpose for me; Your steadfast love, O LORD, endures forever. Do not forsake the work of Your hands.” (ESV) Each of us can have this same confidence, based on the truths of this verse:
— God made you: as this verse asserts, you are “the work of Your hands” – “Your” is referring to GOD. “We are His workmanship”, Eph. 2:10 says. Psalm 139, the very next Psalm, makes this abundantly clear: “You formed my inward parts; You wove me in my mother’s womb.”
— If God made you, then HE will fulfill His purpose for you: “The Lord will fulfill His purpose for me.” NAS translates it: “The LORD will accomplish what concerns me.” Notice it is not that YOU will fulfill your purpose for yourself; you may fail. But GOD will fulfill His purpose for you. Don’t feel the “pressure” as if it all depends on you. It doesn’t. As Romans 9:16 says: “It is not the man who runs or the man who wills, but God who has mercy.”
— As that passage indicates, all of this is based on His grace: “Your lovingkindness, O LORD, endures forever.” “Lovingkindness” is the Hebrew word “chesed”, which is God’s undeserved love and grace. His grace is the basis of His fulfilling His purposes in us. It is not our effort that will in the end succeed in fulfilling His purposes for us, but God’s grace. And THAT should be a comforting note for each of us who knows His grace!
