Nice thought but frankly you can't do it all, because God doesn't want you to treat these tasks as something you can do in a day then check off on a list. He wants to get your hands dirty and be indepth in relationship with people.
Why do you think God gives us specific gifts and experiences throughout our lives? Reflect on that and ask God to reveal to you a specific calling for you based on what hes given you THEN go do it. Not even single people can do everything in thats in the bible. Look at people in the bible. Regardless of whether they were single or married God gave them all a specific task to do- even Jesus himself had to prioritise preaching to the Jews since he knew he wouldnt have time to go on a road trip around Europe and Asia Minor in order to get round to the Gentiles.
I disagree with you in this, Im aware that we cant do everything and God gives us specific experiences and gifts but I dont think is the only thing to do and that we have to only wait sitting without doing nothing until God tells us what to do because He already gave us his word with all the things He likes that we do and there are a lot of ppl around us that we can help and we can have the oportunity to show the love of God and when we are single we have much more time than married to do some things. Im not saying that married ppl should go away from God but single and married have different tasks :
1 Corinthians 7:32-33 " I would like you to be free from concern. An unmarried man is concerned about the Lord’s affairs—how he can please the Lord. But a married man is concerned about the affairs of this world—how he can please his wife"
Because what God likes is that we do good things:
Proverbs 3:27 "Do not withhold good from those to whom it is due, When it is in the power of your hand to do so."
Galatians 6:9-10 "Let us not become weary in doing good, for at the proper time we will reap a harvest if we do not give up. 10 Therefore, as we have opportunity, let us do good to all people, especially to those who belong to the family of believers.
Hebrews 13:15-16 "Therefore by Him let us continually offer the sacrifice of praise to God, that is, the fruit of our lips, giving thanks to His name. 16 But do not forget to do good and to share, for with such sacrifices God is well pleased."
So i dont think we should wait and wait to do the good
