Identity Crisis- Know Thyself
===========================
Before my salvation or rededication to Christ, I became an atheist.
I operated my life on a mishmash of principles and ideologies. Some scientific, some philosophical, some psychological, some Hollywood, some horoscopical and some cultural.
The hardest part was I had to start extenuating myself from these belief systems. I had to begin to renew my mind by replacing them and transforming my mindset with the Word of God.

Why did I bring this up?
Even as an unbeliever, something helped me a lot. An understanding of my identity as a terrestrial being (flesh). Because I came to understand myself as a man, I could operate without religion.
The most significant part of it was knowing my dual nature as a Cusp. Also an understanding of my Temperaments. It helped me manage myself and to understand and manage others too.

Where am I getting at?
Until a believer understands His Identity as a New Creation, he would be tossed to and fro.
Until you understand that you're a triune being (3 in 1) in Christ, you won't be able to Develop your Spirit, Renew your Mind and Discipline your Flesh. That the WHOLE of you may be presented blameless before God. 1 Thessalonians 5:23

Please, Christianity is Discipleship of Christ.
Join the Foundation Classes in your church. Without a good foundation, there's nothing strong to build the structure upon.
It is also a test of Humility. And Grace abounds in Humility.
