Romans‬ ‭4:19‬ ‭NKJV‬‬ And not being weak in faith, he did not consider his own body, already dead (since he was about a hundred years old), and the deadness of Sarah’s womb.

Don’t consider how much money you have.
Don’t consider how many other people tried that same thing, but failed.
Don’t consider your age to go back to school, start a business, or have children.
Don’t consider how long it has taken.
Don’t consider your marital status.
Don’t consider your education, criminal history, or experience.
Whatever the world tells us to consider, don’t consider it.

Our job is to solely focus on and believe God’s word. If He said or promised it, it will come to pass. No matter how long it has taken, remain focused on God’s word.
