My friend David, did you think anyone of those loved ones of yours would come to the Church of the crucified Christ if you yourself did not display Christ-like patience and perseverance through adversity and persecution? Did He not tell us we would have such things, as even He had to endure.
Have strength through Him, for His Word is true and He is the resurrection and the life!
Your family is against you because they are concerned they are going to lose you. They have not been illuminated by the Holy Spirit as you have to see the truth of the (Orthodox) Church. But they should be concerned, for Christ is the Lord, and it is through Him whereby your family is saved and will be saved, and our charge is to pray for them and to show love and mercy on them.
They are fearful, because they love you, and so, we must show love too, in a positive way, and allay their fears. How? Through Christ-like patience and perseverance. Have mercy on your loved ones and understanding, and pray for them. And when they insult, you offer peaceful words of love. When they yell, you speak in a calm and meek way. If they threaten, tell them you love them, with the same love you have for our Father in Heaven. That is the same love and devotion you share with God and with them, and that is why you are converting.
We run the race, not by stepping over our loved one, but through the same love. Want to find peace and joy, then have no fear, but have mercy and patience, and above all love.
Pray to Christ for strength and for patience. Pray to Christ for your family and loved ones. And do not forget that nothing worth fighting for is obtained easily. We do not get to the empty tomb and eternal life without first going through Golgotha.
Have the cross in your mind daily, and learn to see the crosses which manifest through trials in your daily walk. Discern the moments of God protecting you and guiding you and strengthening you through these trials. And praise Him and thank Him for remembering you and strengthening you, even if it were through fire. But it is through fires whereby the gold is purified so that it may reflect the glory of God.
Have Him close to you always in your heart, and you will see all these obstractles and difficulties will be overcome.
