Hardly a theologian here and probably way over my pay grade but I can let you know my understanding of the faith.
Trust seems situational. I may trust you to do something but it does not require faith in you.
Faith seems to have the connotation of moral characteristic.
For example: It is by faith you are safe through grace. Faith implies rust which is unseen (blessed are they who see and believe and yet more blessed are those who believe and do not see). Faith seems to equate with belief
It seems to be that substituting trust for faith does not work as well
Thus I can trust without faith but cannot have faith without trust.
YMMV.
You did well for your own admittance of lacking in training.
I am a firm believer that many times the least of those trained can answer the most honest and come closest to the truth, since you put your faith in God to give you the right answer.
Thank you.
Ditto.
