Everyone has sinned against God: For all have sinned and fall short of the glory of God. Romans 3:23
Sin separates us from God: For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord. Romans 6:23 When Adam and Eve sinned, we became separated from God. No longer could there be that close fellowship God had once had with His special creation, mankind. We deserve to die for ours sins. Even one sin separates us from God. We are born with a sinful nature.
God loves and forgives us: But God demonstrates His own love toward us in that while we were yet sinners, Christ died for us. Romans 5:8 God loved us so much that He was willing to give His one and only Son to die on a cross for all the sin ever committed. Jesus Christ was and is perfect. He had never sinned. And yet, He took the shame of all mankind upon Himself.
Believe and receive Jesus: But as many as received Him, to them He gave the power to become the children of God, to those who believe on His name. John 1:12; Admit that you are a sinner in need of god’s saving grace, then believe on the Lord Jesus Christ.
For by grace are ye saved through faith, and that not of yourselves; not of works, lest any man should boast. Ephesians 2:8-9 You can not work your way to heaven, nor will your good outweigh your bad. In the end, only those who accepted God’s free gift of salvation and grace will spend eternity with Him.
God will never leave you: for He hath said, I will never leave thee, nor forsake thee. Hebrews 13:5b Once you have accepted the marvelous gift of salvation from sin, nothing can take away that assurance that you are saved and a child of God. He will never leave you nor forsake you. You will always belong to Him.
Also, now that you are saved, know that you are a representative of Christ Jesus. Your actions and words will be to others a picture of Christ. If your actions and words do not reflect Christ, others won’t see Him. Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new. 2 Corinthians 5:17
