Romans 8:31 If God is for us, who can be against us? 32 He who did not spare His own Son but gave Him up for us all, how will He not also with Him graciously give us all things? 33 Who shall bring any charge against God’s elect? It is God who justifies. 34 Who is to condemn? Christ Jesus is the one who died—more than that, who was raised— who is at the right hand of God, who indeed is interceding for us. 35 Who shall separate us from the love of Christ? Shall tribulation, or distress, or persecution, or famine, or nakedness, or danger, or sword? 37 No, in all these things we are more than conquerors through Him who loved us. 38 For I am sure that neither death nor life, nor angels nor rulers, nor things present nor things to come, nor powers, 39 nor height nor depth, nor anything else in all creation, will be able to separate us from the love of God in Christ Jesus our Lord.
Yes… when you are a Christian it is as easy as believing what GOD says about you and what HE thinks about you… regardless of what others think or say (Including yourself!).
