True, but to start a journey, you have to have a destination in mind before you can take that first step as well as plans on how to complete that journey. Just taking random steps seems to lead to me stepping off a cliff.
What a negative you have, Bataar. You seem to be finding comfort in your misery.
Of course you don't need a destination before starting a journey. Do you think that God will really lead you over a cliff?
Did Moses know his destination when he was going out from Egypt?
Read Exodus, starting at Chapter 3 and see where it takes you. Moses had no plans at all. SomeOne else was planning his journey and he started out blind. He protested and questioned and doubted and insisted, as you do, that he was the wrong man for the job. He started out with no destination, no provisions, no map or plan. He did obey God, grudgingly, and he never arrived at his destination as a punishment for his doubting. But his people benefitted and we acknowledge his greatness to this day.
Think about how you are going to start your journey. There is no-one in your neighbourhood who needs assistance, a listening ear, who needs her grass cut, etc. etc. Have you particular interests? Can you share them? Take on some practical training. At 44, you may have quite a few year to live. Why not live them instead of moping through them. Get a good health checkup.
