You are never alone. G-d hears your very thoughts even before you have them. He counts the very hairs on your head and has known you even while you were being formed in the womb. He brought you to existence. Even the sparrows are cared for. How much more will He care for you?
Do not lose hope.
Tell Him you trust in Him every day and if you can pray more, tell Him various times, especially when you feel distressed and alone, hopeless or afraid. Say to HIm, "I trust in You." He is with us.
He is Im-Anu-El (Emanuel)...
God, the One with us.
No matter the circumstances, trust in His mercy. Persevere until the end. Do not lose hope if you struggle or even stumble. We all do at times. But get back up again and run towards His mercy.
He is with you...He is with all of us and will NEVER leave us. When you look back on these situations in future, you will see one set of footprints in the sand and those will be the ones of Christ who carried us through it all. Be encouraged and do not fear.
