Ah ok I see your question better.
That becomes a bit nuanced. Did God ASK YOU to sell everything and give to the poor? He asked that question of the rich young man because He knew the man's heart and wanted to reveal it to him. He could have been an Apostle.
God doesn't demand everyone live in poverty. Abraham was wealthy. So was Job, and God restored his wealth. And the world has had a way of becoming more complicated. If you have any family you must provide for, then you cannot give everything away and leave them without provision.
But it is about the heart. We must not be so attached to anything we have above God. What if you know of a need someone has, and you could help, but it will cost you something you wanted? That will help reveal your heart. Or what if you have an opportunity to do something that will benefit you spiritually but you must miss work and lose some income, or take a lesser paying job, to do it? These all reveal to us. And ... we don't have to be perfect.
But different people have different struggles. Some people do tend to be attached to monetary things and find it hard to give. Another person might not have a real inclination to or attachment to wealth. If the second person gives everything up, does that make him somehow "better" than the first? Actually, it doesn't. No more than a person who doesn't like the taste of alcohol and so doesn't drink at all can think he's better than an alcoholic who TRIES not to get drunk but "falls off the wagon" in spite of his struggle. The actual struggle to overcome the flesh has great value. If a particular weakness just doesn't tempt us, that is no virtue on our part. Just a cross we don't happen to bear.
If you're asking these particular questions, maybe you've identified some particular struggle you have. That's good - you know where to start. In that case, if it were me, I would start with little things. Pack a few bags with food, socks, and common needs, and give them when you see people in need. Put aside a little money and find a good way to donate to help needy people with it. Find opportunities to volunteer. Giving helps teach us to be generous, and to love others. It will probably feel good, but it's not the "feeling good about ourselves" part that we want. Find those things that help you be happy for the person getting help, that helps you rejoice with them, that increases your caring about them, and focus on those things. That will begin to change us and our attachments. It's a start. Where we go from there - well I can't say. You might have a particular talent you can apply to such ministrations. Or God might make you aware of another completely different area that needs your attention.
But remember it's not legalism. We CANNOT BUY our salvation. And God isn't looking to bar the door against anyone. He wants all people to be saved. So He will do everything we allow Him to do to help us. Our part is just to cooperate.
Asking particular questions as you have can help us see where we are "sick" or fall short of Christ. Doing something about it is like taking the medicine so God can heal us. It's impossible for us to say "how healed we need to be". That's God's business. But if we cooperate with Him, we know He has all knowledge and has all things in His control, and will indeed complete us in Christ. That's what He does.
