And he who searches hearts knows what is the mind of the Spirit, because the Spirit intercedes for the saints according to the will of God. (ESV)
We tend to be very private people. In many respects we are too private. We think that somehow we can get away with things because no one is watching. What we fail to realize is that God the Father is always watching. It is our Heavenly Father whom the Apostle Paul is referencing when he says, "He who searches hearts."
Consider the words found in 1 Chronicles 28:9: "And you, Solomon my son, know the God of your father and serve him with a whole heart and with a willing mind, for the LORD searches all hearts and understands every plan and thought. If you seek him, he will be found by you, but if you forsake him, he will cast you off forever. (ESV)
The Lord searches all hearts. and he knows what is the mind of the Spirit. The Holy Spirit is the one who is actively interceding for us before the Father. Consider that as believers in Jesus Christ we are now indwelt with the very Spirit of God. He lives within us. He empowers us. He knows us intimately. Every flaw. Every strength. He knows it all.
The Father and the Spirit are in perfect communication and agreement. As the Father searches our hearts he finds the Spirit interceding on our behalf. In 1 Chronicles 28:9 the idea of God searching our hearts is very intimidating. In Romans 8, we are comforted to know that what the Father searches the Spirit intercedes for on our behalf.
Believer in Jesus Christ, the Holy Spirit is actively on your side. Where you have needs and struggles he is interceding to the Father for you.When he searches you he finds the Spirit. Praise His name.
