Be a missionary
Consider becoming a missionary. We'd be glad to talk to you. Life is sometimes difficult even in a comfortable environment but when you serve the Lord you know you are preaching the Gospel of Jesus Christ.
Don't be a "silent witness". Be a real witness. One that reaches out to others...even those who don't love you and tell them how the Lord has transformed your life!
Pray about it. It takes time to consider something like this. But in the meantime, think about being a missionary from where you are. How? By support us with your prayers and finances.
May God bless you as you continue to serve Him.
