DOES A PERSON RISK TO LOSE EVERLASTING LIFE IF HE/ SHE SINS AFTER HAVING BEEN SAVED? LIFE

The answer to this important question is emphatic YES and NO.
NO if you have set your mind and heart to follow Christ. If you have done that and it happens that you have sinned, then most probably it will be an incidence and not a lifestyle. In such a case 1John 2:1-2 applies. ''My dear children, I write this to you so that you will not sin. But if anybody does sin, we have one who speaks to the father in our defence- Jesus Christ., the Righteous One. He is the atoning sacrifice for our sins, and not only for ours but also for the sins of the whole world''.NIV. You will notice  that John employs the language used in our court rooms. Jesus who experienced all the temptations and sufferings of this life and was able to overcome them without sin will have to show the reason why He believes that the temptation was in such a way, such a time and such a version that it was really tricky and hard for you to overcome. Remember there is no explanation that can be easy considering that He Himself overcame all.
YES. You risk losing everlasting  life even after being saved if you said a little prayer of confession and continued in your old lifestyle. Such a life shows that most probably you did not mean what you were saying and deciding. To such a person 2John verse 9 applies: ''Any one who runs ahead and does not continue in the teaching of Christ does not have God; whoever continues in the teaching has both the Father and the Son.''NIV. True repentance will always be like the story we read in the Bible of the prodigal son. When he accepted that he was wrong he did not continue doing wrong. He started down the road toward his father and home. Luke 15:11-32. True repentance is about turning from sin to Jesus Christ, from darkness to light, from the power of Satan to the power of God. The following bible readings shows beyond reasonable doubt that a believer should walk in holiness and newness of life after receiving Christ: Before salvation - Ephesians 2:1-3. After: Eph. 4:17-32, Rom.6:11-14,19,22. Rom.8:6-17, 8:31-38.; 11:19-22; 12:1,2,9-21. 1Cor.3:1-4,16; 5:11; 6:12-20; 9:24-27; 10:1-13; Gal.5:16-26; Php.4-49; Col.3; 1Thes.5:16-24; 1Tim.2:8; 4:1-15; Titus 2:6; Heb.10:26-. James 1:22-; 4:1-.; 1Pet. 3:8-.; 2Pet. 1:3-11. Read full 1st, 2nd and 3rd letters of John and Jude. These are a few scriptures among others that testifies to the truth of the question in discussion. Thank you and God bless and keep you.
