When you come to Christ, you must change. Change is sometimes difficult, but God requires us to become new creatures. (see Romans 6:4) We must not conform to this world, but must be transformed by the renewing of our minds. (See Romans 12:2) A transformation takes place when you become saved. Don’t let anyone make you believe you are the same after God saves you. Your mind has to change. You can’t be stuck and comfortable in your old mindset. You must be willing to go through the process to become the person God requires you to become.
God wants His church to be like Him. What is Christ like? He’s holy, righteous, patient, long-suffering, forgiving, kind, etc. Those are the characteristics that He wants us to exemplify. In the flesh dwells no good thing and it wants to rise up. However, the Holy Ghost will help you control it and to display godliness, but you have to yield to it. Paul told Timothy to be an example of the believer in word, deed, and in conversation.
It is a good thing to be saved and to know that you are chosen by God! God saw and chose you before you saw yourself. You were chosen before the foundation of the world. Once God saves you, you have to learn how to walk and to please God. When you receive the Holy Ghost, you are not immediately perfect. That is why you must learn to live holy and to grow in grace. God’s purpose for His church is that it is holy. It is to be nothing like the world. (See Ephesians 1:4)
We have to live a life of holiness. God expects nothing less. Holiness means we live a life that is separated from the world and for God. When you are baptized in Jesus’ name, you bury your sins and rise up to walk in the newness of life. You are to be different when you get up. You are not to go back to the same thing you were doing before you were baptized. You are to be a visible example to unbelievers. Let others see Christ in you!
We have to believe to the saving of our souls. Once we believed, we were sealed with the Holy Spirit of promise, which is the Holy Ghost. (Ephesians 1:14) You have to have the Spirit of God to go back with God when He comes for His church. The best way to know you have the Holy Ghost is not by speaking in tongues, but by the fruit you bear. You have to show the Holy Ghost in everything you do and in everywhere you go. You must also feed and maintain the Holy Ghost. You must live holy.
