Imagine you have a big puzzle to complete. You can't just sit and wait for someone to finish it for you. You have to work hard and put the pieces together yourself. Once you start working hard to solve the puzzle, you'll notice that it becomes easier and faster for you to complete it.
God works in a similar way. He wants us to work hard toward achieving our goals and dreams. God will not just do things for us without us putting in effort. God wants us to take action, make decisions, and put our best effort into what we want to achieve. When we do these things, God will see our efforts and help us in achieving our dreams.
So, "God helps those who help themselves" means that we should not sit around and wait for things to happen on their own. We need to start working towards our goals and doing our best so that God can help us along the way.
