In reflecting on the Psalm 55 I noticed that it starts with David crying out to God for help in times of distress only to end with him praising God for His character and faithfulness. Like so many Psalms they start with an honest plea, or voice of despair but end with an acknowledgement about who God is. This Psalm in particular caught my attention because of the last two verses.
Cast your cares on the Lord
and he will sustain you;
he will never let
the righteous be shaken.
But you, God, will bring down the wicked
into the pit of decay;
the bloodthirsty and deceitful
will not live out half their days.
But as for me, I trust in you.
This shows two parts of God’s character: His mercy and His Justice. God will not let the righteous be shaken but the evil and bloodthirsty will live short lives. The promise of God is that if we put our trust in Him, nothing will overcome us. This is not to say bad things will not come our way, but that He will be our rock and foundation. If we build on that foundation, we will never see decay.
