How do we know that God's blessings are irreversible?

The certainty of God's blessings is affirmed in Numbers 23:19, where it declares, "God is not a man, that he should lie; neither the son of man, that he should repent: hath he said, and shall he not do it? or hath he spoken, and shall he not make it good?" This assurance signifies that once God has blessed His people, these blessings cannot be taken back or undone. Believers are assured of their security in Christ, as demonstrated in John 10:28-29, where Jesus says that no one can snatch them from His hand, further confirming the irrevocable nature of God's promises.
