The attitude is the biblical attitude for living life. God's Word is faithful; His message is absolute, certain, and guaranteed. God does not vacillate in His message or His plans; neither did the apostles, and neither should we.
Everybody has a choice as to how to think about things. If you choose a negative, wrong attitude, then you will experience negative results. If you choose a positive, biblical attitude, you choose an attitude of faith and you will reap positive results. More than just positive thinking or mind over matter, author Frank Damazio describes an attitude established upon the Word of God.
