Faith is not about being delusional about what is in front of us, it's about being confident in who is with us. It's about realizing all that has been done for us and knowing that since God has called us to a task, He is more than able, more than capable of seeing us through that task regardless of the difficulty of said task. So we recognize the task ahead, but we reminisce and and remember the strength of our God and we remain in faith to move forward.
