We wait for many things... peace, courage, opportunity, understanding, happiness.
But waiting alone accomplishes little to nothing.
It is only when we wait on the LORD (as in invite Him into our situation, both big and little!) that the waiting bears fruit.
Do you know what else I love about that verse up there? It doesn't say that God might strengthen our heart, but that He WILL strengthen our heart!
In my own life, I have seen this come in the form of God giving me heart in areas where I was doing the right things outwardly, but my heart not really being in it. Thinking and doing what the Bible says without truly "feeling" it.
In the weakest points of my life, I have sung the song about the joy of the Lord being my strength. God was and continues to be faithful in allowing my heart to follow this lead of my mouth. It doesn't always happen right away, but it does happen every.single.time.
Is there something that you are waiting for? Are you holding back from doing what you know to be right just because you don't fully "feel" it in your heart? Invite God into your situation, into your life circumstance and let Him strengthen, fill and change your heart!
Joy, strength, courage... we can only get it from our mighty God!
It is worth the wait.
