Psalm 109:21 But you, O God my Lord,
deal on my behalf for your name's sake;
because your steadfast love is good, deliver me!
22 For I am poor and needy,
and my heart is stricken within me.
23 I am gone like a shadow at evening;
I am shaken off like a locust.
24 My knees are weak through fasting;
my body has become gaunt, with no fat.
25 I am an object of scorn to my accusers;
when they see me, they wag their heads.
26 Help me, O Lord my God!
Save me according to your steadfast love!
In many of David's psalms like this one, we find he is facing opposition. He is weary of the way he has been treated by others. He is worn out and down. He can hear the murmurs and see the shaking heads. What do you do with that? Call out to God for help - based not on how good you are, but how faithful and loving God is. By the end of your prayer, you'll be saying with David:
30 With my mouth I will give great thanks to the Lord;
I will praise him in the midst of the throng.
31 For he stands at the right hand of the needy one,
to save him from those who condemn his soul to death.
