Repent (as in, stop and give up your sin) and believe the gospel.
God decided what is right and what is wrong. Repent means to stop fighting against God, and let go of the wrongs (sins) we commit against Him. Sins lead to death and Hell, if we keep them and choose them over God. Either sin or God is your master currently.
There is only one gospel unto salvation: the gospel of Jesus Christ. It is this: that Jesus of Nazareth died for our sins according to scriptures, He was buried, and He was resurrected by God according to scriptures. Jesus of Nazareth is the Son of God, and also God in the flesh. There were many eye witnesses to this, and has been passed down through history. You must believe this.
At this point, have you repented and believed the gospel? Have you completed step one?
If you repented of dead works, which are the sins you previously committed and now believe the gospel, go and be baptized in the name of the Lord Jesus.
Acts 2:38 Then Peter said to them, “Repent, and let every one of you be baptized in the name of Jesus Christ for the remission (forgiveness) of sins; and you shall receive the gift of the Holy Spirit. 39 For the promise is to you and to your children, and to all who are afar off, as many as the Lord our God will call.”
This is done for the remission (removal and debt payment) of sins. The Lord Jesus said to baptize in the name of the Father, the Son, and the Holy Spirit. The apostles immediately obeyed, and baptized true believers in the name of the Lord Jesus! Jesus is the name of the Father, and the Son and the Holy Spirit!
Your sins are then wiped out, by the grace of God! Do not then go out and replace them, or try to hang on to them! That is not the way of the saved! Reckon yourself alive and well to God by keeping from sinning, controlling both your body and thoughts.
If you do this truly, the Spirit of God will come upon you.
The Spirit of God is the Holy Spirit (sometimes referred to as the Holy Ghost). He guides us in all truth, and God’s word is truth. Miracles, signs and wonders will follow you if you are a true believer indeed. Throughout the Bible, people who received the Spirt of God would begin to speak in tongues,, which is a earthly and understood language you don’t know but are able to speak by the power of God. This is one that I had prayed for and experienced personally, in public with confirmation of the language being Hebrew. This was also demonstrated in the Bible by multiple true believers in the New Testament.
From now on, don’t be lazy to study to show yourself approved onto God, a workman who ought not be ashamed, rightfully dividing the word of truth! Those who study will be able to tell the good from the evil, and the intents of the heart. Those who are lazy to do this most likely won’t make it. Salivation is not a one time prayer, and then forget about God. It is a life long, military campaign. The objective is to get to God and truly live holy!
In the name of the Lord Jesus Christ of Nazareth, I bless you to get to know God, to obey Him and to live holy for Him.
