The only promises that you should hold to are those of Christ-like promises.
No promise in the world can keep Gods love away.
Deuteronomy 31:6 “Be strong and courageous. Do not be afraid or terrified because of them, for the LORD your God goes with you; he will never leave you nor forsake you.”
John 6:37 “All that the Father gives me will come to me, and whoever comes to me I will never cast out.”
2 Corinthians 5:21 “God made him who had no sin to be sin for us, so that in him we might become the righteousness of God.”
