Psalm 131 is a beautiful Psalm in the Bible which speaks of humbly trusting in the Lord. So often we try to figure out and manage life and it's struggles on our own. We employ and seek out our own devices and solutions to try to solve life's problems and trials. If we do pray to God for answers, we sometimes ask God to solve our problems and heartaches the way we think is best.
Instead, in Psalm 131 the psalmist says, "I do not concern myself with great matters or things too wonderful for me." We can't understand God's ways. We can not fully understand what He has in mind in the issues and trials of life, but He is so much wiser than us. We can rest in His wisdom. The psalmist goes on to say, "But I have stilled and quieted my soul."
The psalmist has stilled and quieted his soul "like a weaned child with His mother." He is content to just be in and enjoy the presence of the Lord. An unweaned child wants something from the mother. The child wants the mother's milk. The weaned child only wants and desires to be in the presence and company of his mom. He is not looking for what the mother can give him, but he just finds solace and comfort and joy in who the mom is as a person.
So it is with God. We can find joy in His presence alone and in who He is as our loving and faithful God. Psalm 131 tell us, "We can find "hope in the Lord both now and forevermore."
