The first most basic attitude is love. Jesus includes loving God with the first commandment, and loving others as the second commandment:
“36 Master, which is the great commandment in the law? 37 Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. 38 This is the first and great commandment. 39 And the second is like unto it, Thou shalt love thy neighbour as thyself. 40 On these two commandments hang all the law and the prophets.” (Mat 22:36-40 KJV)
