Horatius Bonar emphasizes the dual identity of believers as both 'servants' and 'heirs' of God's heritage, highlighting the blessings that come with this inheritance, including deliverance, peace, and eternal security. He explains that our title to this heritage is secured by God's righteousness, which is divine, righteous, free, and eternal, ensuring that it cannot be lost or diminished. Bonar encourages believers to embrace this gift with faith, warning against the dangers of unbelief that can prevent entry into the promised inheritance. He reminds us that this heritage is a free gift from God, purchased by Christ's righteousness, and invites all to accept it wholeheartedly. Ultimately, Bonar calls for a response of faith to God's invitation to enter into this glorious inheritance.
