Be Sure you are a Christian
You can be sure you are a Christian if you have truly accepted Jesus Christ as your Lord and Savior. The Bible says "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" (Romans 10:9). You have been saved for all of eternity because of your faith in Jesus Christ by the grace of God.
Your feelings will not always echo your salvation. There will be days when you don't "feel" saved. But your feelings don't determine your salvation; your faith in Jesus does. "Yet to all who received Him, to those who believed in His name, He gave the right to become children of God" (John 1:12 ).
"For God so loved the world that He gave His one and only Son, that whoever believes in Him shall not perish but have eternal life. For God did not send his Son into the world to condemn the world, but to save the world through Him."
John 3:16, 17
"Everyone who calls on the name of the Lord will be saved."
"For it is by grace you have been saved, through faith-and this not from yourselves, it is the gift of God-not by works, so that no one can boast."
