6Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God. 7And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus.
1 Peter 5:7
7Casting all your care upon him; for he careth for you.
25Therefore I say unto you, Take no thought for your life, what ye shall eat, or what ye shall drink; nor yet for your body, what ye shall put on. Is not the life more than meat, and the body than raiment? 26Behold the fowls of the air: for they sow not, neither do they reap, nor gather into barns; yet your heavenly Father feedeth them. Are ye not much better than they? 27Which of you by taking thought can add one cubit unto his stature? 28And why take ye thought for raiment? Consider the lilies of the field, how they grow; they toil not, neither do they spin: 29And yet I say unto you, That even Solomon in all his glory was not arrayed like one of these. 30Wherefore, if God so clothe the grass of the field, which to day is, and to morrow is cast into the oven, shall he not much more clothe you, O ye of little faith? 31Therefore take no thought, saying, What shall we eat? or, What shall we drink? or, Wherewithal shall we be clothed? 32(For after all these things do the Gentiles seek:) for your heavenly Father knoweth that ye have need of all these things. 33But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you. 34Take therefore no thought for the morrow: for the morrow shall take thought for the things of itself. Sufficient unto the day is the evil thereof.
13I can do all things through Christ which strengtheneth me.
6So that we may boldly say, The Lord is my helper, and I will not fear what man shall do unto me.
1 Peter 5:10
10But the God of all grace, who hath called us unto his eternal glory by Christ Jesus, after that ye have suffered a while, make you perfect, stablish, strengthen, settle you.
10Many sorrows shall be to the wicked: but he that trusteth in the LORD, mercy shall compass him about.
27Peace I leave with you, my peace I give unto you: not as the world giveth, give I unto you. Let not your heart be troubled, neither let it be afraid.
1Let not your heart be troubled: ye believe in God, believe also in me. 2In my Father’s house are many mansions: if it were not so, I would have told you. I go to prepare a place for you. 3And if I go and prepare a place for you, I will come again, and receive you unto myself; that where I am, there ye may be also. 4And whither I go ye know, and the way ye know.
