Living in the Faith is living in righteousness. It is impossible to have faith in the Truth and live in a Lie. It is impossible to believe the Word of God and do what the devil likes. Unless this faith is religious, emotional or sensationalist.
But when faith is supported by the Word of God’s Wisdom and practiced intelligently, then it is impossible for faith to fail.
The Lord Jesus Christ is the Author and Finisher of the Intelligent Faith, this is, He is the Initiator and the Concluder of the Faith. Because of this, faith and righteousness are inseparable, they walk together. Faith symbolizing man with the image of God, and Righteousness, the Holy God of the Saints.
And isn’t this exactly what the LORD teaches when He says:
But the just shall live by his faith. Habakkuk 2.4
Now the just shall live by faith; but if anyone draws back, My soul has no pleasure in him. Hebrews 10.38
This shows the eternal marriage of faith and righteousness. Faith justifies the sinner.
To live by faith is to live by what is righteous, upright, correct, praiseworthy and pleasing before the Most High. God is Justice and has lent us Faith precisely so that we may live a righteous life, in communion with Him. This is, from faith to faith or from righteousness to righteousness. This kind of faith is what pleases God.
