Believers know they are called by their love for one another and the desire to fellowship with other Christians (1 John 3:14).
The assurance of God's calling is evident in the transformed life of a believer. In 1 John 3:14, it states that we know we have passed from death to life because we love the brethren. This love is a natural outflow of a changed heart, which desires fellowship with other believers and a deeper relationship with Christ. When believers experience the new birth, they are not only justified before God but also gifted with a new nature that produces love, compassion, and unity within the body of Christ. The desire to walk in line with the gospel and reflect Christ's love to others is a clear indicator of being called.
