In Jaffa, there are restaurants that will cook fish that you bring in. So, go to the fish market along the water, pick what you want for lunch, and go back to the restaurant of your choice and have them prepare your lunch. It's a unique experience.
Must visit the Santa Clara and Santa Theresa hotels. Both have superb menus at prices equal to or better than the Juan del Mar "chain" of places to eat. Do the roof top of Santa Theresa about 5:00 pm ... order drinks ... and wait for the sunset about 6:30 pm. View from there is superb.
Tithing is not a pre condition for salvation. That said ... If you believe and turn away from wrong doing, you're on the right path. To love is to give. So, you will end up giving. So, understand that your salvation in Christ is something that unfolds and develops as you grow, turn away from wrong as you learn to let go, and learn to love God and others. So, giving is part of loving.
