To make your religion real, you need to follow these steps:
1. You need to know that you are a helpless, hopeless and condemned sinner and there is nothing you can do to keep you out of hell, because you deserve to go there; that there is absolutely nothing in you that pleases God.
2. You need to acknowledge that Jesus died on the cross and rose again to give you eternal life; that in dying on the cross He took your sinfulness upon Himself and gave you, in return, His pure righteousness to make you acceptable to God.
3. You need to receive Jesus as your Saviour and Lord and give your whole life to Him, acknowledging Him in all your ways, so He can guide your steps.
4. Then you need to start reading the Bible, not as a duty to read a certain amount every day, but to read as much as you can for genuine understanding; and to talk and discuss the issues of your life with God in an open and honest, and real manner, leaving nothing out.
Once you have taken those steps of faith, and you can see that it is more than just saying, "I believe in Christ" which may be no more than just believing that He exists, you can believe the promise that "He who comes to Me I will in no wise cast out." and, "To those who receive Christ, He give them the right to be called the children of God."
Believing the promises of God is an act of the will. If you trust in a religion based on feelings, you will be up one day and down the next. It will just be a roller coaster, bipolar religion. But a religion based on God's promises, which never change, you will have a settled, stable faith, which will result in commensurate actions that will demonstrate that faith.
