What many people think being a Christian is all about;  I can't do certain things and I must do a list of other things.... The do's and the don'ts
Being a Christian is all about having a relationship, being in a relationship with God our heavenly Father.
It is God who calls us to himself, it is God who has done what is necessary. God made everything - it was perfect, perfect in the sense that there was no sin, no pollution, there was no evil. But the devil entered in and he tempted Adam and Eve, he lied to them and they fell for it - and through Adam and Eve's disobedience everything got corrupted and polluted. Man fell, man died - the relationship man had with God was corrupted because of man's disobedience, because man sinned. 
But God who is rich in mercy and out of his great love, sent his only Son Jesus Christ to pay the penalty for our sin, for our rebellion and disobedience​. Jesus took our death, our punishment and through him we can be forgiven and reconciled to God and he can and will become our Father and we his child.
2 Corinthians 5:17-21
So that if anyone is in Christ, he is a new creation; the old things have passed away; behold, all things have become new! And all things are from God, the One having reconciled us to Himself through Jesus Christ, and having given to us the ministry of reconciliation, as, that God was in Christ reconciling the world to Himself, not charging their deviations to them, and having put the Word of reconciliation in us. Then on behalf of Christ, we are ambassadors, as God is exhorting through us, we beseech on behalf of Christ, Be reconciled to God. For He made the One who knew no sin to be sin for us, that we might become the righteousness of God in Him.​​
Go in through the narrow gate; for wide is the gate and broad is the way that leads to destruction, and many are the ones entering in through it.                 Matthew 7:13
