Jesus was chastising the Pharisees, not commending them when he charged that they were practicing the least of the ceremonial ordinance of tithing while neglecting what he called more important tenets of morality and righteousness. Mosaic Law was in place during that time. Nowhere in scripture did Jesus ever pay a tithe, receive a tithe, or leave any instructions for tithing to be normalized under the New Covenant. Today's version of tithing from earned wages to a religious institution carries no biblical precedent. As such, carries no biblical obligation, although there's nothing wrong with choosing to practicing tithing, money or otherwise, to a church or otherwise, as we're able and as we feel led. But we're free to give, not bound to pay.
giving must be cheerful or God wouldn't be pleased. we shouldnt make tithing a burden thus if we feel anxious we are allowed to choose give or not. however, continous anxiety must be dealt with with grace and truth.
