Perhaps you have a hospital appointment tomorrow, or you're concerned about who will care for your impaired child while you're away? You're not sure how life will turn out. At moments like this, I try to remember that God has gone before me and has promised to be with me – no matter what. According to Deuteronomy 31:8, "It is the Lord who goes before you; he will be with you and will never fail or leave you." So don't be afraid or disheartened.”
In difficult circumstances, it is natural to focus on the circumstances around us rather than on God's faithfulness to us. But Jesus was patient with those who questioned Him and did not accuse or blame them. When Thomas questioned the veracity of Jesus' resurrection, he enabled him to touch his wounds and see for himself (John 20:24-29).
When I'm feeling doubtful, I remind myself to trust God rather than rely on my own understanding: "Trust in the Lord with all your heart, and lean not on your own understanding." Submit to him in all your ways, and he will make your pathways straight.” 5–6 (Proverbs 3:5–6)
