No temptation has overtaken you except such as is common to man; but God is faithful, who will not allow you to be tempted to beyond what you are able, but with the temptation will also make the way of escape, that you may be able to bear it.
-1 Corinthians 10:13

Why is there such a thing as temptation? Some people believe that God is the one that tempts you but in reality, He'll never do that to you. It's the devil that cheers you on to sin, but as soon as you do, the devil goes against you and makes you feel guilty. It's true that God tests you, but only what you're capable of. His reasons might not seem logical at the beginning, but He knows why. The feeling of guilt was made so that you'll come to God to ask for forgiveness, but the devil turns it around it makes it so that you'll get away from God like if you're not worthy to be with Jesus. Do not fall into that trap. Always go to Jesus no matter what.
