The Old Testament contains a lot of rules and festivals that God require the Israelite to observe. The Old Testament law is very strict. Anyone that does not obey the law will be punished. In those days, the blood of animal sacrifices is used to atone for the sins of the people of Israelite. This is to show that the blood of animal sacrifices will not be used for sin atonement forever.
Jesus Christ had to come to the earth to die on the cross and make atonement for our sins. Galatians 3:13 records that anyone that is hanged on a tree is cursed. The death and resurrection of Jesus signifies the establishment of the New Testament. By God’s grace, anyone who believe in Jesus Christ can get saved and inherit eternal life. We get saved not as a result of our works, so that we can boast about it. But, salvation is a gift of God. When the New Testament comes into effect, the Law of Moses was abolished so that there is no more need of following them. We are to walk in love and be kind to one another to show that we are good disciples of Jesus Christ.
God says the wages of sin is death. A sinner must repent in order to escape God’s judgment otherwise he will be condemned in hell. There is nothing you can do to please God and get saved except to believe in Jesus and follow him. It can be difficult for a sinner to fulfill the law as he is prone to sin. The seed of sin is in everyone and everyone has a tendency to make mistake. As a result, God had to send his only son, Jesus Christ, to come into the world to die for our sins.
Jesus Christ is God in bodily form while he was on earth. Jesus was vulnerable to all the sufferings just like human. After Jesus Christ was resurrected, he sat at the right hand side of God. Jesus Christ is a mediator between God and men. He intercedes for our sins.
You should not be discouraged if you continue to fall into temptation to sin. Without a conviction, your conscience will become hardened and it will be difficult for you to turn back to God. Waging war with your flesh means that you at least know you are on the good side, fighting against evil. You can pray and ask God to help overcome your sin.
For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast. (Ephesians 2:8-9 KJV)
And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me. (2 Corinthians 12:9 KJV)
For sin shall not have dominion over you: for ye are not under the law, but under grace. (Romans 6:14 KJV)
And if by grace, then is it no more of works: otherwise grace is no more grace. But if it be of works, then it is no more grace: otherwise work is no more work. (Romans 11:6 KJV)
But he giveth more grace. Wherefore he saith, God resisteth the proud, but giveth grace unto the humble. (James 4:6 KJV)
But by the grace of God I am what I am: and his grace which was bestowed upon me was not in vain; but I laboured more abundantly than they all: yet not I, but the grace of God which was with me. (1 Corinthians 15:10 KJV)
But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us. (Romans 5:8 KJV)
