“Worship and serve him with your whole heart and a willing mind. For the LORD sees every heart and knows every plan and thought. If you seek him, you will find him. But if you forsake him, he will reject you forever. So take this seriously. The LORD has chosen you to build a Temple as his sanctuary. Be strong and do the work.” 1 Chronicles 28:9-10 NLT

How do we serve God with a willing mind? It begins with worshiping Him with our whole heart. King David in his last instructions to his son Solomon, soon to be king, were words of encouragement, “And Solomon, my son, learn to know the God of your ancestors intimately. Worship and serve him with your whole heart and a willing mind.” David knew the task of building God’s Temple was before his son, and he wanted to prepare him to be ready not miss out on what God had chosen him to do.
David also warned his son that if he forgets God and goes his own way, it will have severe consequences. The Lord would reject him forever, including his assignment to build the Temple. But isn’t God a God of mercy, you ask, yes, He is, but the one who rejects God, rejects all that God is, His love, His salvation plan, His grace, and yes, His mercy. David didn’t want his son to reject God. His desire for Solomon was for him to know God intimately through worship and serving. David stressed to Solomon to ‘take this seriously,’ and think about who God is and what He had chosen him to him to do above everyone else, build His Temple. I’m sure it was overwhelming for Solomon, but David wraps up by saying, ‘Be strong and do the work.’ The Lord would be with him.
God has a specific assignment for you and me to do. Will we have a willing mind when He reveals His plan to us? To be willing and ready we need to worship Him with our whole heart. The Lord sees and knows what’s in the deepest crevasses of our hearts, so we can’t fool Him. If we wholeheartedly seek God, we will find Him and won’t miss out what He has for us.
