Righteousness through faith 

But for us also, to whom it shall be imputed, if we believe on him that raised up Jesus our Lord from the dead;Romans 4:24

Because of their hardened heart and sinful nature Moses received the Law from God to guide the Israelites against their acts. The Law never made them righteous before God. Those who received the Law received it with fear of not breaking it hence might see the Consequence.

The Bible made Abraham as a perfect case study of one who lived by faith and was called righteous because he had faith in God, though the promises yet fulfilled of him to be a father when his wife was stricken in age, the Scripture made us to understand that this faith made God to declare him righteous Romans 4:22 And therefore it was imputed to him for righteousness.

We can only be righteous if we have faith in God. Just as it is written that without faith it is hard to be holy in the presence of God  Hebrews 11:6 ”But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him.”

Let us grow up from the understanding that the Law will make us sinless and  by our faith in God who raised Christ from the dead Romans4:24

Hoping that Christ is coming again to take us and change us, is another way of having faith in Him thereby our thoughts,actions and ways are guided by the promise of His second coming to receive his saints. I pray that the grace to be steadfast in faith, God Almighty will bestow it upon us in Jesus Christ Name.

Conclusion:

God can only declare anyone righteous if He/She received and believed in his son who is Christ Jesus. Our way to righteous is to be steadfast in faith and not by the Law.
