With the christian or any religious faith; where God asks us to take the leap of faith without challenging his commandment would seem like a very weak and authoritative relationship. Like having an abusive partner telling you to stay in the house without you talking to no onw beside him/her.
In the relationship with God; He expect that we challenge His leap of faith expectation; like a teenager challenging their parents when they do not want their child to do something.
For example of such a situation is when God asked Abraham to kill Issac; Abraham could have challenged God by saying "You gave me this child, and you are saying, "that I must end is life", so wtf why must I do this." and Abraham could easily refuse to kill Issaac. Another example, when Jesus was about to start his trial, and he asked God "Let your will be done, and not mine." Jesus could have save my will shall be done, and not yours.
For a healthy relationship in terms of faith; from time to time we must be able to ask, "If I take this leap, on how will it affect me?" And, I would bet you that God will respond back and tell you why, and if He doesn't I bet he will understand, because taking a leap to the unknown is a very scary, and dangerous move to make.
