If we love one another, God dwells in us, and His love is perfected in us. (1Jn 4:12) God’s love is being perfected, or brought to completion in us, as we express God’s love to others. God is perfecting His love in us by loving others through us, for love is of God, from God: He is the ultimate source of love – the Author of love. (1Jn 4:7)
If we don’t love others then we don’t love God (1Jn 4:20), and if we don’t love God then we don’t know God. (1Jn 4:8)
It isn’t that we could ever earn God’s love by loving others; God’s love is unconditional: it can’t be earned. He loves everyone because He has made them in His image and chosen to love. We don’t grow in Christ’s love by trying harder and denying ourselves, but by beholding the glory of Christ as the Spirit transforms us from glory to glory. (1Co 3:18) As we behold the glory of Christ God reveals Himself in us and to us, until we know experientially His love for Man, filling us with all the fullness of God (Ep 3:19), enabling us to love others.
When we know and believe God’s love for us, since God Himself is love, and as we live each day receiving and expressing this love, we dwell in God and God in us. (1Jn 4:16)
Since love is so central, so fundamental in walking with God, He tells us clearly what His love for us looks like, and also what it means for us to love Him.
We might think loving God is a sentimental thing, a feeling of interest, pleasure or delight at the thought of God. While loving God naturally produces such feelings, it isn’t exactly the same thing, and this may be hard to fully grasp.
So, God explains that His love is much more than sentiment and feeling: His love is perfected in us as we keep His commands; if we don’t keep His commands we don’t love Him. (Jn 14:23)
Loving God is acting as if God is worthy, just and good; disobeying God is rejecting His authority, goodness and wisdom. In disobedience we’re despising Him, not loving Him; those who live like this don’t know Him (1Jn 2:4); it’s in obeying God that His love is perfected in us, accomplishing its purpose; it’s how we know we love Him and belong to Him. (1Jn 2:5) Earnestly obeying God from the heart is loving Him by definition. (1Jn 5:3a)
Torah itself is the perfect written expression of God’s love for us (Ps 19:7a), showing us how He loves us and unites us to Himself (He 8:10), how He transforms us to be in relationship with Himself (Ps 119:50,93); He gave us Torah for our good. (1Jn 5:3b) So, Torah defines both what loving God looks like, and also what God loving us looks like.
While we harbor fear, fear of God’s displeasure because we’re willfully disobeying Him (He 10:26-27), or fearing and resenting His authority in our lives because we don’t believe He’s good (Is 33:14), or fearing what others might do to us because we doubt God’s sovereignty and justice (Mt 10:28), then we aren’t yet made perfect in love. (1Jn 4:18)
Obedience also isn’t merely about outward observance to ritual and mechanical rules; nor is it about honoring God with just our lips. If our hearts are far from Him, if we’re not in awe of Him (Ps 4:$), seeking His face, rejoicing in Him, loving God with all our heart, soul, mind and strength, it isn’t obedience at all (De 6:5): it’s nothing. (Mt 15:8)
In living out God’s love, ordering our steps in His Word so iniquity has no dominion over us (Ps 119:33), the purpose of God’s love is accomplished, completed and perfected in us; this gives us boldness before God on Judgment Day because we’re living divine expressions, incarnations of God in this world. (1Jn 4:17) In so abiding in God we have confidence, and aren’t ashamed before Him at His coming. (1Jn 2:28)
Bringing all of these concepts together shows us God’s love has a purpose or a goal: to conform us to the image of Christ (Ro 8:29), the very goal of Torah. (1Ti 1:5) When we love God, we will want to be like Him (Mt 11:29), and walk as He walked. (1Jn 2:6)
Knowing God’s love for us enables us to walk in benevolence, mercy and love toward all, wishing ultimate good for everyone, as God does. (Mt 5:44-45) We don’t love because others are good, but because they’re made in the image of, and loved by perfect Goodness. (1Jn 4:21)
The more we behold and grasp the love of God, the more completely we’re able to display God’s heart towards others as He loves them through us. (Ro 5:5) We love Him, and therefore others, because He first loved us. (1Jn 4:19)
