We know we are heirs of God through our adoption as His children, evidenced by the Holy Spirit in our hearts.
Scripture indicates that believers can be assured of their status as heirs of God through the presence of the Holy Spirit, which signifies their adoption into God's family. Romans 8:15 speaks of receiving a spirit of adoption, allowing us to cry out, 'Abba, Father.' This deep relationship confirms that if we are children of God by grace, we are co-heirs with Christ. The relationship between our inheritance and Christ's is so binding that any inheritance accorded to Christ directly applies to us. Hence, our assurance as heirs comes not from our merit but from God's promise and the work of the Holy Spirit in our lives.
