What is the definition of faith? It's in the Bible, Hebrews 11:1, TLB. "What is faith? It is the confident assurance that something we want is going to happen. It is the certainty that what we hope for is waiting for us, even though we cannot see it up ahead."
Jesus is the source of faith. It's in the Bible, Luke 17:5, TLB. "One day the apostles said to the Lord, 'We need more faith; tell us how to get it.'" Romans 10:17, NIV says, "Consequently, faith comes from hearing the message, and the message is heard through the Word of Christ."
Real faith is believing in what Christ has done for us. It's in the Bible, Romans 5:1, TLB. "So now, since we have been made right in God's sight by faith in his promises, we can have real peace with Him because of what Jesus Christ our Lord has done for us."
Faith is trusting God in everything. It's in the Bible, Hebrews 10:38, TLB. "And those whose faith has made them good in God's sight must live by faith, trusting Him in everything. Otherwise, if they shrink back, God will have no pleasure in them."
Weak faith can become strong faith with God's help. It's in the Bible, Mark 9:24, TLB. "The father instantly replied, 'I do have faith; oh, help me to have more!'"
