2 Peter 1:3-4 According as his divine power hath given unto us all things that pertain unto life and godliness, through the knowledge of him that hath called us to glory and virtue: Whereby are given unto us exceeding great and precious promises: that by these ye might be partakers of the divine nature, having escaped the corruption that is in the world through lust.
Does God break His promises to us? Can we push Him to His limit until He says, "That's enough! I have had it with you! I'm done."? Is there a breaking point with God? Will He give up on His children?
We can see that through Jesus, and His sacrifice that our sins have been forgiven. We know that because of what God did for us there is no more sacrifice needed for our sin. God has taken care of it! What a wonderful thought! What a great promise!
Hebrews 10:10 By the which will we are sanctified through the offering of the body of Jesus Christ once for all.
Read that one again. Did you notice that because of His sacrifice for you, you are sanctified. Not one day, but right now. Not positionally, but practically. There is nothing that could sanctify you like the offering that Jesus himself made for you on Calvary. God promises that this was enough. He hasn't gone back on it yet, but we will get to that.
Romans 6:3-6 Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death? Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life. For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection: Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin.
The death, burial and resurrection of Christ involved you. You may not understand all of it but it is very clear that when Christ died, your old nature died with Him. When Christ rose, newness of life and spiritual resurrection is available to you through faith in His finished work. The passage says you were baptized into his death. There is no mention of water here. It is saying that you were immersed (baptized). This promise is a massive game changer. I do not need to crucify the flesh, or my old nature. It was done for me on the cross. I now have the freedom to walk in the Spirit and in newness of life. This a great promise but does God ever break it? Nope!
Let's look at one more promise.
1 John 2:12 I write unto you, little children, because your sins are forgiven you for his name's sake.
God has promised that those who are adopted into His family, by being born again, are forgiven. Their every trespass is blotted out by the blood of Christ and has been removed forever.
Colossians 2:13-14 And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses; Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross;
The forgiveness provided at salvation is a once-for-all forgiveness of your sin. There is no "bar of soap" for Christians after salvation. The scripture is abundantly clear: God has forgiven the believer of all trespasses.
So.... can he break His promise? I believe it is a matter of if He will or not.
II Corinthians 1:20 For all the promises of God in him are yea, and in him Amen, unto the glory of God by us.
It appears that these promises are contingent upon one thing: God. In fact, all of God's promises in the New Covenant are as sure as Jesus' performance for you and his finished work that He is now done with and sitting at the right hand of his father. Child of God, you have nothing to worry about, it wasn't based on you keeping your promises, it's based on God keeping His word, and according to the verse above all of His promises are yes and yes in Christ.
