Faith is believing that things will be better even if you cannot see it. Faith is completely trusting everything to God.
Therefore I tell you, whatever you ask for in prayers, believe that you have received it, and it will be yours - Mark 11:24
We should always learn to see the good in every situation. We must always train our minds to see the good in everything. That is faith. God is the best planner and everything we have been through is not a waste of time because we are getting closer to what God has prepared for us.
To place our faith in God means we need to spend time getting to know Him through the Bible and through prayer and through community. Faith in God is built up over time and we build and grow in our relationship with Him. This faith in Him helps us give Him thanks in the good times and the bad, and to weather the storms of life.
This shows how much we truly love and believe in the Lord God. Our faith, our belief in Him will save us. We have not seen Him personally yet we believe in Him and trust Him. This faith strengthens the bond we have with the Lord. Faith shows who the real ones are, who truly believes in Him regardless of the negative things people say about Him.
