Psalm 20 is all about having trust in the Lord. Trusting him to protect you, trusting in his salvation, and trusting that he hears you and will grant you your heart’s desires and fulfill your plans.
It is okay to be a little scared, but remember who your God is. He is for you and wants to see you victorious in the battles you face.
Are you currently facing a battle? Are you having problems with money, work, marriage, relationships, health, etc.? If so, I encourage you to read Psalm 20 as a prayer over the battle you are currently facing, and trust that God will bring about his good purposes in your life. Also, this Psalm, although it was written by David, it is a prayer being prayed on his behalf as he enters battle. If you are in a battle, ask others to pray for you as well. God will be faithful to answer.
Part of trusting in the Lord is getting to know him better, and what better way than by reading his word? Grab your copy of Celebrating Psalms – Book 1 to begin the journey.
