I wouldn’t look at it as a test because even after you pass the first test, there will be another test and another one, probably for the rest of your life.
God says in the bible 1st Corinthians 10: 13; “No temptation has overtaken you except what is common to mankind. And God is faithful; he will not let you be tempted beyond what you can bear. But when you are tempted, He will also provide a way out so that you can endure it”
Look at it like this. Pretend you are a boxer. (And like all christians, you will grow into becoming a really tough fighter that never gives up) God is the referee. He will never let you take more than you can bear. If you get knocked down, He will ask you “Do you want to get up and continue”.
Even if you get knocked down 200 times in a day, it’s up to you to make that decision of not giving up and continuing to get back up. As long as you keep believing no matter how many times you get knocked down that your going to win, you are saved(a true child of God) and you will definitely go heaven.
Yes, you can be anything you want. In the bible Mark 9: 23;Jesus says “If you can? Everything is possible for one who believes”
As a child of God, Jesus has made it possible for you to do anything. It’s the devil who wants to take that gift away from you because he knows what you can do. The devil wants you to feel unmotivated, hopeless, confused, he even wants you to doubt God.
But remember who you are. You were made in the image of God, so nothing is impossible. If anytime you feel down, remember that it’s the devil trying to confuse you and stop you from going any further.
