How do we know that love is essential for Christians?

Several passages in Scripture affirm that love is not just an ideal but a command that stems from the nature of God Himself. 1 John 4:7 declares, 'Beloved, let us love one another: for love is of God; and every one that loveth is born of God, and knoweth God.' This indicates that love is intrinsic to being a Christian, as it confirms our relationship with God and our identity as His children. Furthermore, the act of loving others demonstrates our obedience to God's commandments and serves as a testimony to the world of Christ's love through us.
