"Delight yourself in the Lord,” is not merely being happy. Believers need to be submissive and pliable in His hands, being happy to serve and to please Him in such a way that it delights their heart."
Amen! Such a good text! And this also delights the heart of our Father, who will gladly give such a child the desires of his/her heart! Because the child desires what God desires and what is pleasing to Him, because the child have the same heart.
I believe Moses is a good example of a man who knew God's heart and desired what God desired and therefore he got God's full attention. That's why he was able to speak so boldly to God and God did what he asked. He even said that God should repent..! (Ex. 32:12). And God did repent. (Ex. 32:14) Because he truly knew God's heart and was a friend of Him. Wow.
