Whereunto I am appointed a preacher, and an apostle, and a teacher of the Gentile. For the which cause I also suffer these things: nevertheless I am not ashamed: for I know whom I have believed, and am persuaded that he is able to keep that which I have committed unto him against that day. Hold fast the form of sound words, which thou hast heard of me, in faith and love which is in Christ Jesus. That good thing which was committed unto thee keep by the Holy Ghost which dwellleth in us. Titus 1:11-14
 
For God has no given us the spirit of fear; but of power, and of love, and of a sound mind. 2 Timothy 1:7
