Krish,
start by praying asking guidance. no one can evangelize unless one is living the life. the world is too much in our daily lives. it is a constant struggle just to stay afloat. the struggle is the "conviction" to those who do not believe. the world does not understand the difference between carnality and spirituality. most do not know they have a soul. That is why I wrote do good, kindness. do good to all. show you are a child of God and God will reward you.
If you are wanting to go out and find out what it's like, you have to understand that each person has a soul and it belongs to God. Each soul is the image of the Living God. There are all kinds of back blasting comments:
1 why does God allow evil?
2 why does God not grant me the million dollar business?
3 why does God allow killing of innocents?
4 why do some Christians live like us?
Answers:
1 God did not create evil -- Book of Wisdom explains
2 God is not going to grant some one power who is still an adolescent
3 God does not allow needless killing unless it is for a good cause. The cause is many things. Here are a few: to show that evil is alive and well and His name is Satan. Two sides good and evil. Free will, just as man chose to not listen to God in Eden, man continues to not listen to God and kills innocent people because they were seduced by evil and His name is Satan. An evil person is carnal towards God they blame rather than seek help, true guidance, peace, love, joy, holiness. This all has to do with man not knowing, knowing is knowledge.
4 They are not fully convinced of God, or they are once saved always saved and they feel they can go and live as the world does. Under false pretense, not knowing.
Bottom line to all this is lack of true knowledge of God. The world is vortex sucking souls in through vice, lusts of the eyes, and flesh and pride of life.
To convince someone they are going to eternal damnation, you need to go in the power of God. Stay in a state of Grace. Sanctifying Grace spills over onto others as you live your daily life. A person in a state of SG, is always under Gods great bounty and power, that power is light and love to the world. To get to the point where everything you do is a prayer, is when souls will yield to Gods power. Because the light is attractive in a soul who is living for God. There will always be those who oppose, because they are pawns of Satan. Prayer is the key and while meditating listen to God. Once you have learned His Voice, it becomes your guide. That is why everything you do in life should be a prayer. Prayer is more than just talking to God from the mouth. It is talking to God with your soul, your soul talks to God through action as well. Meditating on God clears your soul of clutter; Prayerful life speaks to God by mouth and heart and soul and body. That is why Jesus said to love God with all your heart, mind, soul and strength. Because your a living prayer. Hope this helps.
Love always the Trinity and Holy Mother of God.
