I think you should become baptized as soon as you have an opportunity. some will never get the time to be , but if there is occasion, take it and follow the Lords command.
Tithing is right and there is a prescription laid out in the word. from beginning to end.
In general, tithing has been abused by the money grabbers and they have polutted the system of tithing. you can ID them by their favorite scripture (Mal 3:10) They call us God robbers.
If you go to the word and follow the examples of giving of your tithe and following God and leaving man behind you find a lot of freedom to tithe. and then it is not such a burden as we have been brain washed to believe in.
my opinion only
