Following Christ Is Not Simply a Decision

Making a decision to follow Christ cannot save you any more than being baptized can, neither praying a prayer nor walking an aisle can free you from the wrath of God that is to come.

Only REPENT of your sins and BELIEVE the Gospel.

Repentance is not only a mere apology, but a TURNING AWAY from sin, an agreement with God that we are wicked sinners, unable to please Him on our own, and belief is not simply a head knowledge that God is real or that Jesus existed, rather TRUSTING fully in the completed work of Christ to save us from our sin, allowing the Holy Spirit to direct your thinking and your actions through the Word of God (The Bible), anything else is done in vain.
Apart from Christ salvation is impossible.

Ezekiel 36:26-27
"Moreover, I will give you a new heart and put a new spirit within you; and I will remove the heart of stone from your flesh and give you a heart of flesh. "I will put My Spirit within you and cause you to walk in My statutes, and you will be careful to observe My ordinances.
