Having faith is having trust. You have to trust with your entire being that God has your back that he will help you and take care of you. He knows what is best, but to truly embrace what he has planned for you, you have to fully trust. Our trust is not foolish, for our God is both faithful and good. Dig into Scripture. Acquaint yourself with the promises of God, with his longsuffering faithfulness to the Israelites, to Abraham, to us all. Get to know the character of God and your joy and willingness to trust in Him will abound.
“Trust in the Lord with all your heart and lean not on your own understanding; in all your ways submit to him, and he will make your paths straight” – Proverbs 3:5-6
