Ongoing love is a matter of teaching truth, ministering to the needs of others, serving one another, covering faults, forgiving, enduring, and sacrificing for others. It’s a debt that Christians owe to one another, made possible by the love of God shed abroad in their hearts by the Holy Spirit.
Love is the comprehensive grace that includes everything in terms of Christian living, fulfilling the law and demonstrating a bottom line for understanding God’s whole law. It is possible to fulfill the law through love, and love is the fulfilling of the law, as seen in the Ten Commandments and the teachings of Jesus Christ.
