It does not matter if your are a new Christian or a mature Christian, because when it comes to personal evangelism, all Christians have the same interest and concerns. If you are a new Christian and want to tell your unsaved family members, unsaved friends or even an occasional stranger about Jesus Christ and the need to accept Him as their Savior, you do not have to know the entire bible.
What is most important is to know that to say to tell unsaved people about salvation in Jesus Christ and the need to accept Him as Savior. In my book " WHAT TO SAY EVANGELISM" is a prepared and easily learned, one of a kind salvation gospel presentation that will instantly create a desire in any unsaved person to want to hear the salvation gospel of Jesus Christ and when they hear it, they will accept Jesus as their Savior almost 100% of the time.
Almost everyone is interested in the things of God, even the lost and unsaved. They may not openly say it, but they are, because all unsaved people are afraid of death. They do not know what to expect at death. It is the great unknown and fear of death is the greatest fear that mankind has and everyone is interested in the answer to the question of "what happens when they die." The exciting thing about this unique salvation gospel presentation is that it introduces coming death in a gentle way and in a way that unsaved people are instantly prepared to want to hear about biblical answers about death. When you begin presenting this salvation gospel you are in Godly authority, because Jesus Christ Himself, gave you this authority in Matt 28 19 "Go therefore and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit." When any unsaved person hears this salvation gospel presentation they will closely listen, follow along and at the end of it will want to and will pray to accept Jesus as their Savior. As a man, woman or mature teen the Lord has called you to lead or win unsaved people to their own decision to accept Jesus Christ as their Savior. Satan will try and attack you by whispering in your ear the lie that "you cannot share your faith or win or lead an unsaved person to Christ because you are new in the things of God. Do not let him intimidate you. Rebuke him by proclaiming "get behind me Satan." You do not have to be a biblical scholar to win or lead an unsaved person to Christ.
In John 4:1-42, the Samaritan woman at the well knew almost nothing about Jesus Christ other than that He revealed Himself to her as the Messiah. She ran into her hometown of Sychar and told many of the men what Jesus told her and many believed in Him. It does not matter if you have been a Christian for a day, a week, a month, a year or 10+ years. When you learn this one-of-a-kind salvation gospel presentation you will be powerfully prepared to share your faith with the goal of actually leading or winning unsaved people to accept Jesus as their Savior.
