"How do true Christians differentiate themselves from other religions when practicing Christianity?"
 
First,

Ture Chistians MUST worship God in truth - John 4:24.

Eternal life is knowing the Father, the only true God, and Jesus Christ whom He sent - John 17:1, 3.

In relation to Jesus' words, true Christians teach the truth to their neighbors in this life-saving essential area.

Second,

By making the Father's name known and teaching others to use it as a holy name, true Christians are following Jesus' words:

Declare the Father's name and help make it known as holy - John 17:26 and Matt. 6:9 ('Father ... may your name be held holy' - NJB).

(CEV) Matthew 6:9 You should pray like this: Our Father in heaven, help us to honor your name.

(TEV) Matthew 6:9 This, then, is how you should pray: 'Our Father in heaven: May your holy name be honored;

(BBE) Matthew 6:9 Let this then be your prayer: Our Father in heaven, may your name be kept holy.

(GodsWord) Matthew 6:9 "This is how you should pray: Our Father in heaven, let your name be kept holy."

(ISV NT) Matthew 6:9 "Therefore, this is how you should pray: 'Our Father in heaven, may your name be kept holy.

(Wey NT) Matthew 6:9 "In this manner therefore pray: `Our Father who art in Heaven, may Thy name be kept holy;

(Holman Christian Standard Bible) "Therefore, you should pray like this: Our Father in heaven, Your name be honored as holy.

(The New Living Translation) Pray like this: Our Father in heaven, may your name be honored.

(New Century Version) So when you pray, you should pray like this: 'Our Father in heaven, may your name always be kept holy.

(Easy-to-Read Version) So when you pray, you should pray like this: 'Our Father in heaven, we pray that your name will always be kept holy.

(World English Bible) Pray like this. 'Our Father, who is in heaven, may your name be kept holy.

Third,

Jesus declares the most important commandments: (1) Must Love God (2) Must love neighbor - Luke 10:25-28 (and who is our neighbor? Even the 'hated' (by Jews) Samaritan - Luke 10:29-37).

So even though much of Christendom hates them, don't true Christians need to show love to their 'neighbors' by actively trying to share the essential truths taught by Jesus and the scriptures? Isn't that following Jesus' teachings?

Yes, even though there are going to be "many" who proclaim Jesus as their Lord (Matt. 7:21-22) but still continue along the wide road leading to destruction (Matt. 7:13), shouldn't true Christians be out there trying to help these 'neighbors' learn the truths taught by Jesus and the inspired scriptures? - Matt. 28:19, 20.
