Depending on the Lord’s grace and resting in His finished work does not mean doing nothing. Just look at Apostle Paul, who lived by God’s grace. He saw first-hand how a revelation of God’s grace turned him into the effective and hardworking apostle that he was (1 Corinthians 15:10).
How do we rest in the Lord and still find ourselves effectively doing what we need to do? It’s simple—just do what you ought to do, but do it trusting in the Lord’s favor, not in your smarts or careful planning.
Whatever you need to do today, do it with an inward rest, without worrying or fretting, knowing that He loves you, is in charge and is for you.
For example, let’s say that you’ve got a job interview coming up. First, commit the matter to the Lord. Ask Him for wisdom and favor. Then, prepare for the interview—read up on the company. On the day of the interview, dress appropriately and go for it, all the while having an inward rest as you trust the Lord for His wisdom and favor. As you do what’s needed, He will guide you and empower you to do what’s really needful and right. He’ll also give you favor with your interviewers.
Beloved, rest in His grace today and let the Lord lead you to good success!
