Faith is the foundational element to Christianity. It is through faith that we enter into a personal relationship with the Lord. How we think and act (our very conscience) have to be rooted in genuine faith. Our faith in Christ causes us to then live according to His principles and precepts. After these things, we then have to live a life characterized by faith.
For therein is the righteousness of God revealed from faith to faith: as it is written, The just shall live by faith. Romans 1:17 (KJV)
As Christians, we have to live by faith. What does that mean? Am I to live without a care or concern? Do I live as someone who is a part of a utopian society? NO. Living by faith simply means to live in a manner where you expect God’s continual direction and deliverance. You must trust that God cares for you.
Casting all your care upon him; for he careth for you. 1 Peter 5:7 (KJV)
Regardless of what situations you may be confronted with, you can rest in knowing that God knows all things. He will give strength in hard times, peace in troubling times, provision in lean times, and protection all the time. He will give you mercy and grace to help, in spite of your greatest needs.
Let us therefore come boldly unto the throne of grace, that we may obtain mercy, and find grace to help in time of need. Heb 4:16 (KJV)
One has to live knowing that God will never lie or deceive His people. He will always be a present help in the time of storm.
Let your conversation be without covetousness; and be content with such things as ye have: for he hath said, I will never leave thee, nor forsake thee Heb 13:5 (KJV)
Faith in God does not make anyone exempt from troubles. Oftentimes, it will place us in the center of it. However, the Christian who lives by faith knows in their very conscience that God will never leave them nor forsake them.
