Manny, To many, “faith” simply means having a religious belief or following a form of worship. As used in the Bible, however, “faith” basically means total trust—complete, unshakable confidence in God and his promises. It is a quality that marks a disciple of Jesus Christ.
It is not something that we are born with, nor is it to confused with being gullible. Whereas a young child might accept that the sun will rise from a different direction, if told so, others with more knowledge cannot be fooled. In the same way faith must be based on accurate knowledge.“Faith,” says the apostle Paul, “is not a possession of all people.” (2 Thessalonians 3:2)
To develop faith and trust in someone, you need to know him and to learn how he thinks and acts. This process involves the heart as well as the mind. It is really the same when it comes to developing true faith in God. You need to get to know him, to learn about his qualities and his personality, to find out how trustworthy and dependable he has proved to be in all that he has said and done.—Psalm 9:10; 145:1-21.
Some have acquired faith simply by observing the universe around them. For many, that in itself gives enough evidence to convince them that there must be a Creator. (Psalm 19:1; Isaiah 40:26; Acts 14:16, 17) They feel, as the apostle Paul did, that “[God’s] invisible qualities are clearly seen from the world’s creation onward, because they are perceived by the things made, even his eternal power and Godship.”—Romans 1:20; Psalm 104:24.
To build real faith in the Creator, however, you need something else that he has provided —God’s inspired Word.It is only through the pages of the Bible that Jehovah presents his side of things, so to speak. He sheds light on such perennial questions as why he has permitted suffering and pain and what he will do about the situation. (Psalm 119:105; Romans 15:4)
It is not enough, however, simply to have a Bible or even to believe that it is inspired. “Faith,” writes the apostle Paul, “follows the thing heard.” (Romans 10:17) Hearing the Bible, not just having a Bible, is what builds faith. You “hear” what God has to say by reading and studying his Word.
The next step that cements your faith is to "exercise" it. - John 3:16. This involves becoming a doer of the word.
(James 2:26) Indeed, just as the body without spirit is dead, so also faith without works is dead.
