On the one hand...
"Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates?" II Cor 13:5
Also...
"Ye lust, and have not: ye kill, and desire to have, and cannot obtain: ye fight and war, yet ye have not, because ye ask not.
Ye ask, and receive not, because ye ask amiss, that ye may consume it upon your lusts." James 4:2-3
And then...
"Blessed are they which do hunger and thirst after righteousness: for they shall be filled." Matt 5:6
