and be found in Him, not having my own righteousness, which is from the law, but that which is through faith in Christ, the righteousness which is from God by faith;
Philippians 3:9 (NKJV)
Today, if there is one thing in our salvation that we should rejoice in, it is that we have no conditions to fulfill. It is God Himself who, in His sovereignty and His love for us, has decided to save us and to justify us in His son, despite the state of our sins.
Most of us believe that we should work to earn God's grace, such as doing good deeds, having good conduct, trying to obey the law, not reacting to insults from others, etc. Let me tell you today that none of our actions, however good they may be, can justify us before God or make us merit His grace.
You and I are downright sinners, lost in their sins. God is naturally just, but we are not. This is why He chose to give His son so that He could declare us righteous in His court. David understood this so well that he said in one of his prayers: “Lord, if you kept a record of our sins, who, O Lord, could ever survive?" (Psalm 130:3, NLT) No one would resist the wrath of God if He decided to judge us according to His justice and not according to His love for us.
You have therefore only one thing to do, not to merit the grace of God, but to receive it, and that is to believe in the sacrifice of His son and to have faith in Him.
