Insights from 1 Samuel 30:1-6. David and his men have returned home (after being sent away by Achish, King of Gath (chapter 29), to find Ziklag burned by the attacking Amalekites (v3). Not only is Ziklag in ruins, but they have taken the women and their sons and daughters away as captives.
They wept at what they found on their return. Tears turned to anger and some of the people think of stoning David (v6). Then we read:

Now David was greatly distressed …  But David strengthened himself in the LORD his God. 1 Samuel 30:6b NKJV

David then summons Abiathar the Priest to bring the Ephod. David goes to God to seek His counsel (8). His request is specific: “Shall I pursue this troop? Shall I overtake them?” God tells David to go after the Amalekites. Victory was theirs. All that was taken was recovered (v18).
All around David was nothing but hard things to deal with. He could have gotten so discouraged as to just sit in a corner and get depressed. Instead he “strengthened himself” in God.
Hebrew meaning of the word “strengthened”:

  • to be or grow firm or strong
  • to make firm; to seize, keep
  • It is a word frequently used to describe battle scenes.

Sometimes it’s a battle to look away from my desires for food to God. David did things differently. He does not look around at his circumstances. He does not get depressed and give up and do nothing. No. David turns to the One who can help. The One who knows what to do. The One who will give him direction and stability.

His first action after first feeling distress over the whole situation is to enquire of God. God met him in his need and tells him to pursue. David’s action, with God’s backing, resulted in success.
What do I do when I struggle with overeating? It is my immediate action to go to God in prayer about it? Or do I give in and eat. If I’m bored, or stressed, or things aren’t going right what do I do? Am I like David, or do I medicate myself with food? David didn’t think about what to do next, he went to God. 
Victory comes from trusting God for the journey and knowing, with full confidence, that He will meet me with His love and His direction.
