Telling your loved one to join your religion as a Christian, it clearly shows love and care which you have for them. You have found peace in the place of God and you definitely want them to also have the experience. Is like a good meal which you have tasted and it feels good and you want to share it with your loved ones. This act of leading them to the way of God shows the love and care you have for them.
Bro Eli teaches us about sharing our faith, but we can not force anyone who refused to believe in God. Even Jesus never forced anyone to believe in him. He only teach and lead by example. The bible encourages us to love one another and also teach them why they need to follow Christ.
At this point we can convince our loved ones to join our religion (Christianity) where they will get peace of mind. But we cannot force them to do so. Faith has to be a choice they make themselves. Your job is to love them, live your faith openly, and let your life show them why it’s meaningful. Sometimes, that speaks louder than words.
