1 John 4:12, “No one has ever seen God; but if we love one another, God lives in us and his love is made complete in us.”

Interesting points:
1. In this verse John reminds his readers of an important truth: no person has ever seen God in His full divine essence. Even Moses saw only the back of God (Exodus 33:18–23). However, God's love is made manifest -- allowing humanity to "see" Him -- through the actions of His people.

2. When we are walking in God's love, we demonstrate Him to ourselves and to others. God abides in those who seek to love Him. We do not need to physically see Him since we know He is already in us.

3. Furthermore, God's love is made perfect or complete in us. This does not mean we become sinless. Instead, the focus is on maturity or the quality of love in us. We can find no greater love than God's love. We believers experience God's love inside of us and offers us everything we need to live for Him and to love others. In contrast to the teachings of false teachers, we do not need to seek another experience, person, or teaching: the love of God is sufficient.

Application:
Brothers, while we are assured that we will see our Heavenly Father at His appointed hour, what a joy it is to know that our walk with God is one that draws us progressively closer to Him. As we learn to love one another with our Savior’s sacrificial love, our selfish nature enters a process of transformation. We gain insight and comfort in learning what it truly means to love and be loved.

Although this transformational process will experience setbacks along the way, we can rest assured that the good work that God began in us will carry it on to completion until the day of Christ Jesus when we will finally meet our Lord face to face!
