Just because God didn’t answer your prayer doesn’t mean He failed you. When He says He will never fail you, He will never let you fall when you trust in Him. It’s like sitting in a strong chair trusting it to hold you up no matter how heavy the weight. The Lord is faithful to bear you up and be your strength. You can trust Him, you can rest in Him, and put all of your weight on Him. He can handle it. He won’t let you down.
