Pray everywhere, lifting up holy hands, without wrath and doubting. — 1 Tim 2:8
The true worshippers shall worship the Father in spirit and in truth: for the Father seeketh such to worship him. God is a Spirit: and they that worship him must worship him in spirit and in truth.—Then shalt thou call, and the Lord shall answer; thou shalt cry, and he shall say, Here I am.—When ye stand praying, forgive, if ye have ought against any.
Without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him.—Let him ask in faith, nothing wavering. For he that wavereth is like a wave of the sea, driven with the wind and tossed. For let not that man think that he shall receive anything of the Lord.
If I regard iniquity in my heart, the Lord will not hear me.—My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous: and he is the propitiation for our sins.

My heart panteth, my strength faileth me. — Ps 38:10
Hear my cry, O God; attend unto my prayer. From the end of the earth will I cry unto thee, when my heart is overwhelmed: lead me to the rock that is higher than I.
He said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me. For when I am weak, then am I strong.
When (Peter) saw the wind boisterous, he was afraid; and beginning to sink, he cried, saying, Lord, save me. And immediately Jesus stretched forth his hand, and caught him, and said unto him, O thou of little faith, wherefore didst thou doubt?—If thou faint in the day of adversity, thy strength is small.—He giveth power to the faint; and to them that have no might he increaseth strength.—The eternal God is thy refuge, and underneath are the everlasting arms.—Strengthened with all might, according to his glorious power.
