If you trust God doing what he says is not so hard.
If you trust God and believe in him all things you do for him you shall be blessed God will never ask you to do wrong and what he tells you or does for you is for a reason, at first you might not like what he's telling you to do but you can trust him. According to the Hebrew Bible, God commands Abraham to offer his son Isaac as a sacrifice. After Isaac is bound to an altar, a messenger from God stops Abraham before the sacrifice finishes, saying "now I know you fear God." Even though he didn't want to do this he still did believing in God.
