What is your response to seeing the great evil and wickedness of the world. When it wears you down and you struggle to find the energy to do what is right. But right you do, and you can't help but get frustrated at the way everyone around you behaves...
Your response could be to forget that this would be you unless God intervened and lifted you out of the pit. This then leads to prideful boasting, as if you somehow had something to do with your own salvation!
You, who were blind to spiritual truth, how did you see for the first time unless you were healed miraculously? Just remember that God had no good reason to save someone as sinful as you, and if it weren't for His unmerited favour and mercy, He might just have let you descend and decay into worse evil than that around you which pains you so.
Thank God for saving you! Praise His glorious name and speak of His glory with much gratitude to those who frustrate you. And pray that you would keep the humble perspective when you grow weary of this world, and pray for Jesus to come quickly.
