You can't be a believer if you don't have faith. Faith pleases God. It is an important element in a Christian life. It releases the blessing of God but it's not a way to manipulate Him. It's not a power by which we make God do what we want. It's not a magic!
Faith is not hope but instead faith is to believe in something or someone with full trust.
Faith in God is having the trust and confidence in Him. That in whatever circumstances life may bring, you rely and trust in Him that He can make a way especially when there seems to be no way.
Have faith and let your faith arise!
Here is why faith is so important:
Ephesians 2:8 "For by grace you have been saved through faith. And this is not your own doing; it is the gift of God."
James 2:17 "So also faith by itself, if it does not have works, is dead."
First Thessalonians 1:2-3 "We give thanks to God always for all of you, constantly mentioning you in our prayers, remembering before our God and Father your work of faith and labor of love and steadfastness of hope in our Lord Jesus Christ."
Titus 11:1-2 "Paul, a servant of God and an apostle of Jesus Christ, for the sake of the faith of God's elect and their knowledge of the truth, which accords with godliness, in hope of eternal life, which God, who never lies, promised before the ages began."
Hebrews 11:6 "And without faith it is impossible to please him, for whoever would draw near to God must believe that he exists and that he rewards those who seek him."
Romans 10:17 "So faith comes from hearing, and hearing through the word of Christ."
Matthew 14:30-31 "But when he saw the wind, he was afraid, and beginning to sink he cried out, "Lord, save me." Jesus immediately reached out his hand and took hold of him, saying to him, "O you of little faith, why did you doubt?"
