Excerpts From: Grace – the power of the Gospel
The Gospel is the most basic, foundational message of the New Testament, yet it’s the most misunderstood. Today’s religious system is not preaching the same Gospel that Paul did. They mix it with the Law, and that isn’t the Gospel at all.
It is offensive to people, particularly if they have a lot of holy actions to their names, when you tell them that all their good deeds don’t make them righteous before God. Then when you tell them sinners who only put faith in God are more righteous than they are (Matt. 21:28-32), that really puts them over the top!
We need a Savior! The only thing we have to offer is faith. We just believe the nearly-too-good-to-be-true news that Jesus died for us and paid a debt we couldn’t pay and gave us a righteousness we couldn’t earn. It’s faith righteousness!
It takes a supernatural revelation by the Holy Spirit to be able to understand this. But once you do, it’ll transform the way that you view God, the way that you relate to God, and the way that you receive from God. The Gospel is the power of God unto salvation. I encourage you to just humble yourself and ask God for a supernatural revelation of this truth. It’s tremendous.
When you truly get a hold of the grace of God, I guarantee you, it sets you free from sin, not free to sin. You’ll wind up living holier accidentally than you ever have on purpose. You’ll serve God out of love stricter and stronger than you ever would have out of legalism.
Jesus said you shall know the truth and the truth shall make you free (John 8:32). It’s not truth that sets you free; it’s the truth you know that sets you free. But before you can know it, you’ve got to hear it. Faith comes by hearing and hearing by the Word of God (Rom. 10:17).
Quote from : “Whose Righteousness?”
The word “righteousness” has become a religious cliché that has lost its meaning to many people. Even Christians are confused about what righteousness is and how to receive it.
“Righteousness” and its counterpart, “righteous,” appear 540 times in 520 verses of the Bible. In contrast, “faith,” “faithfulness,” and “faithful” are only used 348 times in 328 verses. This means that there are 1.5 times as many scriptures about righteousness as there are about faith. Righteousness is important.
The mistake of thinking that doing right makes us right is the same error the Pharisees made. Religion has always preached that if we clean up our actions, our hearts will become clean too. Jesus taught just the opposite (Matt. 23:25-26). It’s through a changed heart that our actions change. The heart is the issue. Actions are only an indication of what is in our hearts. Actions are the fruit the heart produces.
Modern-day Christianity often puts the emphasis on actions instead of issues of the heart.
Jesus was in right relationship with God as no one else can be. He is the Son of God. He is God manifest in the flesh (1 Tim. 3:16).
In return for Jesus taking our sin, those who put their faith in Him get His righteousness instead of their own.
Colossians 2:6 says, “As ye have therefore received Christ Jesus the Lord, so walk ye in him.” That means if you were saved by putting faith in God’s grace alone, then you maintain that relationship in the same way.
Failure to understand this truth is at the root of all guilt and condemnation. Satan’s only inroad into our lives is sin. If we understand our right standing with God on the basis of what Jesus did for us, and not by our own actions, then Satan’s power to condemn is gone.
