"1Let not your heart be troubled: ye believe in God, believe also in me." (John 14: 1)
Our one work is to believe on Him whom the Father has sent for us (John 6: 29)
For a long time, I never believed that Jesus would take care of me every day.
I was convinced that I had to take care of everything.
Yes, He died for my sins, but I never knew that He lives in me and through me and for me, that He ministers on my behalf:
"Who [Jesus] is made, not after the law of a carnal commandment, but after the power of an endless life." (Hebrews 7: 16)
What is He doing now?
"What shall we then say to these things? If God be for us, who can be against us? 32He that spared not his own Son, but delivered him up for us all, how shall he not with him also freely give us all things? 33Who shall lay any thing to the charge of God's elect? It is God that justifieth. 34Who is he that condemneth? It is Christ that died, yea rather, that is risen again, who is even at the right hand of God, who also maketh intercession for us." (Romans 8: 31-34)
He intercedes for us, He ministers on our behalf.
My understanding of Jesus was way too small.
Paul better explains everything:
"15Who [Jesus] is the image of the invisible God, the firstborn of every creature: 16For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him: 17And he is before all things, and by him all things consist. 18And he is the head of the body, the church: who is the beginning, the firstborn from the dead; that in all things he might have the preeminence. 19For it pleased the Father that in him should all fulness dwell; 20And, having made peace through the blood of his cross, by him to reconcile all things unto himself; by him, I say, whether they be things in earth, or things in heaven." (Colossians 1: 15-20)
Jesus holds all things together. There is nothing that exists which He did not create.
In the beginning was the Word, Jesus (John 1: 1)
Our peace is based on the fact that Jesus Christ took our sins and has made us fully and forever righteousness in Himself:
"4But God, who is rich in mercy, for his great love wherewith he loved us, 5Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved;) 6And hath raised us up together, and made us sit together in heavenly places in Christ Jesus: 7That in the ages to come he might shew the exceeding riches of his grace in his kindness toward us through Christ Jesus." (Ephesians 2: 4-7)
"For he is our peace, who hath made both one, and hath broken down the middle wall of partition between us; 15Having abolished in his flesh the enmity, even the law of commandments contained in ordinances; for to make in himself of twain one new man, so making peace; 16And that he might reconcile both unto God in one body by the cross, having slain the enmity thereby:" (Ephesians 2: 14-16)
Now, Proverbs records the following:
"Keep thy heart with all diligence; for out of it are the issues of life." (Proverbs 4: 23)
There is a demand placed on us.
With the New Covenant, we receive a new heart, a new spirit, one based on His grace, because of Jesus' death and resurrection
In the New Testament, under the New Covenant, Paul writes:
"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." (Philippians 4: 6-7)
He is our God, and He is a God to us. As long as we believe on Him, then we receive from Him.
Yet some of us still have troubled hearts concerning certain matters.
I submit that in those areas, we are operating under a lie that those matters must be dealt with by ourselves. We assume that whether it's our job, our finances, our friends and family, or anything else, we must take care of those issues.
The more that we see how great Jesus is, that He ministers on our behalf, that He wants to take care of all things, and that we need not bring anything of our own effort to effect anything, then the more of His grace that we receive.
We are called to believe on Him whom the Father has sent to die for us, to live for us, to minister on our behalf at the right hand of God the Father.
Keep seeing more of Jesus, see that He has put away all your sins, even your thoughts and feelings, and that He has reconciled you to Himself and seated you in Himself.
The more that you grow in grace and knowledge of the Lord, the less that your heart will be troubled.
