You cannot love God without first obeying the Truth and knowing Him.
“In Him you also, when you had heard the word of truth, the gospel of your salvation, and had believed in Him, were marked with the seal of the promised Holy Spirit; this is the pledge of our inheritance toward redemption as God’s own people, to the praise of His glory.” Ephesians 1:13-14 (NRSV)
“He said to him, “‘You shall love the Lord your God with all your heart, and with all your soul, and with all your mind.’ This is the greatest and first commandment. And a second is like it: ‘You shall love your neighbor as yourself.’ On these two commandments hang all the law and the prophets.” Matthew 22:37-40 (NRSV)
“When the Spirit of truth comes, He will guide you into all the truth; for He will not speak on His own, but will speak whatever He hears, and He will declare to you the things that are to come. He will glorify me, because He will take what is mine and declare it to you.” John 16:13-14 (NRSV)
It is absurd to say you love God without loving the Truth. If you are not engaging your mind in your pursuit of knowing God you are not really loving God. You are not really obeying the greatest commandment.
