The most important things you can learn at this time is who you are, who God is and what is your relationship with Him.
Who you are:
You are a created being, created in the image of God (who is Spirit), you were created to care for the earth and worship and serve God in holiness and perfection for all eternity. You are also a fallen being, in the past some humans sinned and caused God's wrath to come upon mankind, sin spread like a cancer and has infected every human since. You, me and everyone else on earth is infected with this disease called "sin". Sin is anything contrary to the holiness of God or a perversion (transgression) of something that is good.
Who God is:
God is the creator of all things including time, matter, spirit, life and everything else. He is Three Persons yet One being, He is Father, Son and Holy Spirit, these three Beings make up the One God. He is perfect in every way, holy and just in all He does. The bible proclaims that above all God is HOLY and LOVE. He is love itself, God is love, a Consuming Fire of HOLY LOVE. He is the Judge of all the earth, He demands holiness, but saves the ungodly, He is merciful, gracious and loving to all who call upon Him in truth.
Your relationship with this God:
To be in relationship with the TRUE God you must come to know Jesus Christ as your Lord and Saviour. Because we are sinners God cannot commune with us, we are sold under sin and in bondage and lost, we are under God's wrath for the evil we have done:
"He that believes on the Son has everlasting life: and he that believes not the Son shall not see life; but the wrath of God stays on him." (John 3:36)
"I said therefore to you, that you shall die in your sins: for if you believe not that I am He, you shall die in your sins." (John 8:24)
You must make a decision to believe in Jesus Christ as your Saviour from the wrath of God and from inevitable eternal separation from His presence and salvation. He died in your place and paid a price that you could never pay. Jesus alone lived a sinless, holy life and died as the Atonement for the sins of the world. Study the Old Testament and how the death of Jesus was represented through the Hebraic sacrificial system in the Temple. Jesus is the final, complete and eternal sacrifice for the sins of man, His blood cleanses us from ALL sin and we are declared righteous before the Father because of Him through faith.
If your heart is to know the truth and to know God through Jesus Christ He will save you, continue to study, read the word, especially the gospels and pray to Jesus Christ to save your soul, He loves you. God bless.
"That if you confess with your mouth, "Jesus is Lord," and believe in your heart that God raised him from the dead, you will be saved. For it is with your heart that you believe and are justified, and it is with your mouth that you confess and are saved." (Romans 10:9,10)
