Faith in God is crucial to our walk. “Behold the proud, His soul is not upright in him; But the just shall live by his faith.” (Habakkuk 2:4) “For in it the righteousness of God is revealed from faith to faith; as it is written, ‘The just shall live by faith.’” (Romans 1:17) “But that no one is justified by the law in the sight of God is evident, for ‘the just shall live by faith.’” (Galatians 3:11)
Repentance doesn’t matter if we don’t have faith in God. The Bible says that we are saved by faith. “For by grace you have been saved through faith, and that not of yourselves; it is the gift of God.” (Ephesians 2:8) The faith we have to believe in God was given to us. God gave us the ability to believe in him. “So then faith comes by hearing, and hearing by the word of God.” (Romans 10:17) The faith to be saved was given to you. We are told to pursue faith: “But you, O man of God, flee these things and pursue righteousness, godliness, faith, love, patience, gentleness.” (I Timothy 6:11) And we see in Abraham, the father of our faith, that though he did a thousand things wrong, he did one thing right: he believed God, and it was counted to him for righteousness.
For what does the Scripture say? “Abraham believed God, and it was accounted to him for righteousness.” (Romans 4:3)
…just as Abraham “believed God, and it was accounted to him for righteousness.” (Galatians 3:6)
And the Scripture was fulfilled which says, “Abraham believed God, and it was accounted to him for righteousness.” And he was called the friend of God. (James 2:23)
Faith is how we receive Grace. It’s how we receive the promises of God. The fight is a fight of faith. “Fight the good fight of faith, lay hold on eternal life, to which you were also called and have confessed the good confession in the presence of many witnesses.” (1 Timothy 6:11) The devil is defeated. The fight is a fight of faith. We have to fight unbelief, fear and doubt. We have to fight against the things that would keep us from believing God’s promises.
