First welcome to this forum and to the fold that God is putting together by means of His Son... and which is called the Church.
You are I understand very new as a Christian believer, but God helps any that really believe whether they are new or young or old. Already your experience in the difficulties for the flesh of a believer may well exceed that of anyone else on this forum.
I can tell you to step out in faith, but you are the one who must come to know in your heart more so than in your mind what that means. God will certainly stand by a sincere heart, but that may not mean that He will prevent any persecution from coming your way. Please read this account of Stephen a young man who loved God, but became the first Christian martyr described in scripture. I am showing only the very final verses of the chapter which show how he died:
Act 7:51 Ye stiffnecked and uncircumcised in heart and ears, ye do always resist the Holy Ghost: as your fathers did, so do ye.
Act 7:52 Which of the prophets have not your fathers persecuted? and they have slain them which shewed before of the coming of the Just One; of whom ye have been now the betrayers and murderers:
Act 7:53 Who have received the law by the disposition of angels, and have not kept it.
Act 7:54 When they heard these things, they were cut to the heart, and they gnashed on him with their teeth.
Act 7:55 But he, being full of the Holy Ghost, looked up stedfastly into heaven, and saw the glory of God, and Jesus standing on the right hand of God,
Act 7:56 And said, Behold, I see the heavens opened, and the Son of man standing on the right hand of God.
Act 7:57 Then they cried out with a loud voice, and stopped their ears, and ran upon him with one accord,
Act 7:58 And cast him out of the city, and stoned him: and the witnesses laid down their clothes at a young man's feet, whose name was Saul.
Act 7:59 And they stoned Stephen, calling upon God, and saying, Lord Jesus, receive my spirit.
Act 7:60 And he kneeled down, and cried with a loud voice, Lord, lay not this sin to their charge. And when he had said this, he fell asleep.
I present those words not to discourage you but so that you may understand that you are not the first to come to God and His Son, Jesus, under very difficult conditions. I am praying for you and your family as you walk this rough pathway toward Jesus.
