How do we know God's provision is reliable?

Our assurance of God's reliable provision stems from His immutable nature as the self-existent One, as declared in Isaiah 42:8. God does not change and is always faithful to His promises. Abraham's faith was firmly based upon the understanding that God honors His covenant, which gives us confidence that His provision will never fail. In Romans 8:32, we see that God, who did not spare His own Son, ensures that all other provisions will follow in accordance to His will for those who are called according to His purpose.
