What is a Christian?
Someone only is a Christian if they have been born again by the Holy Spirit of God, brought to saving faith in Jesus Christ and have repented of their sin.
Saving faith is someone receiving and resting on Christ alone for salvation, trusting in His death to save them from their sin.
To repent is to come to have hatred for your sin and to turn away from it and to turn to Christ to follow Him as your Lord in a life of new obedience.
It is absolutely crucial that you are a true born again Christian because only they will go to heaven after death. All other people go to hell forever.
Jesus is a loving Saviour who calls you to come to Him today in faith and repentance so that you will know forgiveness for your sin and a new and eternal life in Him.
Matthew 7:21–23
I Never Knew You
21 “Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but the one who does the will of my Father who is in heaven. 22 On that day many will say to me, ‘Lord, Lord, did we not prophesy in your name, and cast out demons in your name, and do many mighty works in your name?’ 23 And then will I declare to them, ‘I never knew you; depart from me, you workers of lawlessness.’
