First, loving God requires knowing Him, and that knowledge begins with His Word. It may sound glib, but to know Him is to love Him.
To love God is to worship and praise Him. "It is written: 'Worship the Lord your God and serve him only'" (Luke 4:8). The book of Psalms provides many beautiful examples of how to worship and praise our Creator (e.g., Psalms 8, 19, 23, 24, 67, 99, 117, and 150).
To love God is to put Him first. The number-one commandment is to love God “with all your heart and with all your soul and with all your mind and with all your strength” (Mark 12:30). It’s an undivided love. God is our priority. If we love God with all our hearts, souls, minds, and strength, then we won’t allow other things to crowd in. Our love for God is manifested by loving people (Mark 12:31), but we do not love the things of the world. “Earth has nothing I desire besides you” (Psalm 73:25). We cannot love this present world and God at the same time (1 John 2:15); love for what the world offers can lead us astray (2 Timothy 4:10).
To love God is to desire Him, to yearn for His righteousness, His Word, and His grace. “As the deer pants for streams of water, so my soul pants for you, O God” (Psalm 42:1). Once we have tasted and seen that the Lord is good (Psalm 34:8), we want more of Him. If we love God, we will be like Mary of Bethany, “who sat at the Lord’s feet listening to what he said” (Luke 10:39). If we love God, the psalmist’s description of the Word of God will resonate within us: “[it is] more precious than gold, than much pure gold; . . . sweeter than honey, than honey from the comb” (Psalm 19:10).
Suppose a man is separated from his sweetheart and receives a letter from her. His first action will be to eagerly open the letter and pore over its contents. His love for his beloved will naturally cause him to love her correspondence with him. The same is true with our love for God’s Word. Because we love the Author, we love His message to us. We read it avidly and often, we hold it close, and we hide its words in our hearts.
Finally, to love God is to obey Him. Jesus tells us, “If you love me you will obey what I command” (John 14:15, 23; 15:10; 1 John 5:3). However, this is not a matter of merely following rules and registering good deeds. It is about having God’s love written indelibly on our hearts. We naturally wish to please those we love. When we love God, we will want to please Him and obey His commands eagerly. “I delight to do your will” (Psalm 40:8).
