To Know Him Is to Love Him
We are told in Scripture that "We love Him, because He first loved us" (1 John:4:19). Our loving God, then, has much to do with our understanding of who He is and what He's done for us. Out of that comes an overwhelming appreciation and thankfulness that increases our love for Him.
The process of growing in one's love for God, i.e., with all thy heart, soul, mind, and strength, can only come about by learning about Him, and then living out the things that He says. Jesus said, "If a man love me, he will keep my words: and my Father will love him, and we will come unto him, and make our abode with him" (John:14:23).
The personal intimate relationship with Jesus that I hope we all want to see deepened will happen only as we grow in our knowledge of our Lord by spending time with Him in His Word.
