Be careful for nothing

Yes, if you are within, one within the Lord Jesus and his Father, the God of Hosts, then there is no care that you should have.
The Lord will take care of you, because you are his worker, only to be guided by him and only to be recompensed by him.

“If you abide in me, and my word abides in you, you shall have what you wish” [1PE 15:7 KJV]

The bible also tells us how to ask for the things we want, and from which ‘position’, from a position of no care, without worry.

[PHP 4:6] Be careful for nothing, but in everything by prayer and supplication with thanksgiving let your requests be known unto God. (KJV)

Have no care, do not worry about it. For Your Father who knows your most hidden desire has already laid out everything for you in this world.

[1PE 5:7] Casting all your care upon him; for he careth for you. (KJV)

Ask in Prayer and supplication (you must be like little children… remember how you used to ask your parents for that toy, harassing them with total conviction that he could get it for you if they wanted… so also you must ask your Almighty Father… with total conviction )
Give thanks to God before receiving, because you know that he can and will do it, you give thanks before receiving.

[JOH 15:7] If ye abide in me, and my words abide in you, ye shall ask what ye will, and it shall be done unto ye. (KJV)

This is simple and straightforward, Our Father, the God of Hosts is saying that if you stay within him (be obedient) and let his words abide in you (keep the law) you can ask for whatever you want, and he will give it to you abundantly.

Enter into the Lord, have no care or fear.

Father, let the Holy Spirit increase everywhere, in Jesus name.

World without end Father, in the name of Jesus.
World without end, AMEN.
