God does everything in the New Covenant for the believer.

He began the work of salvation and He will complete it.

Philippians 1 “6 being confident of this, that he who began a good work in you will carry it on to completion until the day of Christ Jesus.”

He chose us before the world began to be holy, blameless, forgiven all sin by faith in Christ.

Ephesians 1 “³ Praise be to the God and Father of our Lord Jesus Christ, who has blessed us in the heavenly realms with every spiritual blessing in Christ. ⁴ For he chose us in him before the creation of the world to be holy and blameless in his sight. In love ⁵ he predestined us for adoption to sonship through Jesus Christ, in accordance with his pleasure and will— ⁶ to the praise of his glorious grace, which he has freely given us in the One he loves. ⁷ In him we have redemption through his blood, the forgiveness of sins, in accordance with the riches of God’s grace ⁸ that he lavished on us. With all wisdom and understanding, ⁹ he made known to us the mystery of his will according to his good pleasure, which he purposed in Christ, ¹⁰ to be put into effect when the times reach their fulfillment—to bring unity to all things in heaven and on earth under Christ…..¹³ And you also were included in Christ when you heard the message of truth, the gospel of your salvation. When you believed, you were marked in him with a seal, the promised Holy Spirit, ¹⁴ who is a deposit guaranteeing our inheritance until the redemption of those who are God’s possession—to the praise of his glory.”

God says “I WILL” many times in the New Covenant: (It is not our efforts but His power)

Hebrews 10 “10 And by that will, we have been made holy through the sacrifice of the body of Jesus Christ once for all. 11 Day after day every priest stands and performs his religious duties; again and again he offers the same sacrifices, which can never take away sins. 12 But when this priest had offered for all time one sacrifice for sins, he sat down at the right hand of God, 13 and since that time he waits for his enemies to be made his footstool. 14 For by one sacrifice he has made perfect forever those who are being made holy. 15 The Holy Spirit also testifies to us about this. First he says: 16 “This is the covenant I will make with them  after that time, says the Lord.I will put my laws in their hearts,  and I will write them on their minds.” 17 Then he adds: “Their sins and lawless acts I will remember no more.” 18 And where these have been forgiven, sacrifice for sin is no longer necessary.”

God says:

• He made us Holy and perfect by Christ’s death on the cross.
• He has forgiven us past, present, and future sins
• He will never remember our sins anymore
• He will write His love in our heart
• He is our God and we are His people
• He is our Father and we are His children

Hebrews 8:10-11 “I will be their God, and they will be my people. No longer will they teach their neighbor, or say to one another, ‘Know the Lord,’ because they will all know me, from the least of them to the greatest.”

2 Corinthians 6 ““I will be a Father to you,    and you will be my sons and daughterssays the Lord Almighty.””

Because God does everything: He predestined us, called us, we believed, He justified us, He glorified us. There is no condemnation for us in Christ. Nothing can separate us from the love of Christ:

Romans 8 “²⁸ And we know that in all things God works for the good of those who love him, who have been called according to his purpose. ²⁹ For those God foreknew he also predestined to be conformed to the image of his Son, that he might be the firstborn among many brothers and sisters. ³⁰ And those he predestined, he also called; those he called, he also justified; those he justified, he also glorified.³¹ What, then, shall we say in response to these things? If God is for us, who can be against us? ³² He who did not spare his own Son, but gave him up for us all—how will he not also, along with him, graciously give us all things? ³³ Who will bring any charge against those whom God has chosen? It is God who justifies. ³⁴ Who then is the one who condemns? No one. Christ Jesus who died—more than that, who was raised to life—is at the right hand of God and is also interceding for us.^“

God keeps us blameless until the last day. HE DOES THE WORK.

Jude “24 To him who is able to keep you from stumbling and to present you before his glorious presence without fault and with great joy— 25 to the only God our Savior be glory, majesty, power and authority, through Jesus Christ our Lord, before all ages, now and forevermore! Amen.”

1 Thessalonians 5 “²³ May God himself, the God of peace, sanctify you through and through. May your whole spirit, soul and body be kept blameless at the coming of our Lord Jesus Christ. ²⁴ The one who calls you is faithful, and he will do it.”
