A.I believe when some of us are faced with insurmountable odds we lack the faith we need to trust God, when life problems become so cutting we look to other solutions to help solve our issues instead of just trusting God.
B. The characteristic of a disciple who retains robust faith is simply one whom , Trust in the Lord with all their heart and they lean not unto their own understanding, they wait on they for He shall renew their strength. Their faith is strong, because with faith it is impossible to please God, Now faith is the substance of things hoped for and the evidence of things not seen.
