Stone 3 = grace. David knew God’s grace had saved him from a lion and a bear, enabling him to win those battles. David also gave credit to God for gracing him with skills and ability (as recalled in 1 Samuel 17:34-37). By God’s grace, David turned away from his brother Eliab (1 Samuel 17:30) and this enabled him to position himself to focus on the ‘real’ battle.
We can be easily distracted by smaller grievances and become entangled in these, instead of calling out to God to pour His grace, faith and love upon us (1 Timothy 1:14). This positions us to walk through the current battle we are in.
Pause and consider: How do I recognise God’s grace? When have I seen God’s grace support me in previous battles? When have I offered grace to others?
Grace is a very cool stone to have in a sling. Who can I sling it toward today?
