A promise is a promise! One of my pet hates is when people break their promises - what about you? You know this already, but let me remind us that the Scriptures are filled with loads of awesome promises.
God loves promises.
What is even better is that God also delights in keeping His promises!
Remember when he said to Jacob: "I am with you and will watch over you wherever you go, and I will bring you back to this land. I will not leave you until I have done what I have promised." - Genesis 29:15
And God kept this promise! He will keep his promise to you too. Trust Him.
