Welcome to the forums!
You have certainly come to the right place as you will find all you need to know on budgie care here.
The information on the several articles and sticky threads at the top of each section of the forums will be extremely useful and of benefit to you and your budgie.
If your Enoch shows definite signs of curiosity towards you and moves to closer to where you are while in the cage, then you can take the first steps in the training process. At this point and given the fact Enoch is still frightened when you change the food/water, you can try to do this by avoiding sudden moves with your arms/hands and act as if you are in slow motion.
You can start by offering a tasty treat through the cage's bars, by doing so your budgie will slowly start to get used to your hand/finger.
By looking at his general behaviour and by interpreting his body language you will be able to have a better idea on when to proceed further with training.
When Enoch is confident in eating the treats through the cage's bars and nibble on your fingers, you can then slowly place your hand inside the cage and to give him the little treat with the goal to encourage him to step on to your hand/finger.
If you haven't done so already, be sure to check the info on the stickies here at the Taming and Bonding section.
Best of luck with everything!
