Romans

My brethren, count it all joy when ye fall into divers temptations;

That I may know him, and the power of his resurrection, and the fellowship of his sufferings, being made conformable unto his death;

And because ye are sons, God hath sent forth the Spirit of his Son into your hearts, crying, Abba, Father.
