The exact phrase is not in the Scripture. I personally do not use it in evangelism. I prefer to quote the Scripture directly and let it do the lion's share.
Romans 3:20-24
20For by works of the law no human being will be justified in his sight, since through the law comes knowledge of sin.
The Righteousness of God Through Faith
21But now the righteousness of God has been manifested apart from the law, although the Law and the Prophets bear witness to it— 22the righteousness of God through faith in Jesus Christ for all who believe. For there is no distinction: 23for all have sinned and fall short of the glory of God, 24 and are justified by his grace as a gift, through the redemption that is in Christ Jesus, 25whom God put forward as a propitiation by his blood, to be received by faith.
Luke 24:46-47
"Thus it is written, that the Christ should suffer and on the third day rise from the dead, 47and that repentance and forgiveness of sins should be proclaimed in his name to all nations"
John 14:6
6Jesus said to him, "I am the way, and the truth, and the life. No one comes to the Father except through me.
Acts 4:12
12And there is salvation in no one else, for there is no other name under heaven given among men by which we must be saved."
Ephesians 1:7
In him we have redemption through his blood, the forgiveness of our trespasses, according to the riches of his grace,
Romans 10:9-13
if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved. 10For with the heart one believes and is justified, and with the mouth one confesses and is saved. 11For the Scripture says, "Everyone who believes in him will not be put to shame." 12 For there is no distinction between Jew and Greek; for the same Lord is Lord of all, bestowing his riches on all who call on him. 13For "everyone who calls on the name of the Lord will be saved."
Acts 26:20
repent and turn to God, performing deeds in keeping with their repentance.
However, that does not mean it is wrong to say such a thing, for it is obviously true that salvation is personal.
For it is written:
40Then two men will be in the field; one will be taken and one left. 41 Two women will be grinding at the mill; one will be taken and one left. 42Therefore, stay awake, for you do not know on what day your Lord is coming. 43 But know this, that if the master of the house had known in what part of the night the thief was coming, he would have stayed awake and would not have let his house be broken into. 44Therefore you also must be ready, for the Son of Man is coming at an hour you do not expect.
Matt 24:40-44
And while I do consider Jesus Christ my friend, I believe that we must relate to Him first and foremost as King of kings as a sovereign/patron form of relationship.
