John 15 comes to mind.
.
6If anyone does not abide in Me, he is thrown away as a branch and dries up; and they gather them, and cast them into the fire and they are burned.
7If you abide in Me, and My words abide in you, ask whatever you wish, and it will be done for you. 8My Father is glorified by this, that you bear much fruit, and so prove to be My disciples. 9Just as the Father has loved Me, I have also loved you; abide in My love. 10If you keep My commandments, you will abide in My love; just as I have kept My Fathers commandments and abide in His love. 11These things I have spoken to you so that My joy may be in you, and that your joy may be made full.
John 15:1-11 NASB
For context.
Might want to read it a bit closer.
