I had a friend that was a grandma and she told me one day how the family was so excited that her grandson was finally getting married. 36 years old, found his life partner. I asked how she felt about being a great grandmother and her reply floored me. She said they they are never going to have children together because between the 2 of them they have 7 children by different partners.
Just let that sink in.
Honor God with your singleness, with your dating, with your married life. There are no regrets with God.
You would like to find the love of your life and be married one day. Today is the day you honor her, by not sleeping around. Today is the day you pray for her, that she make good choices, that she also is honoring God. Imagine on your wedding day that you can tell your wife that you loved her long before you even met her, you prayed for her, that you honored her with your dating. That is the man you are called to be. That is the witness that you can give to the women you date. Let them see what a man of God looks like. Let them see in you how God loves them.
Have confidence in God. When I read your post I thought of Peter how he got out of the boat when Jesus called him, but then he looked at the wind and the waves and was afraid. He began to sink. Those parables aren’t just stories, it’s our lives being lived today. Tell our Lord to strengthen your resolve to follow Him. You don’t need to be afraid of those things. It’s the lies that satan whispers. They aren’t true. He will lead people to crash and burn, have regrets. You don’t have to go that route. God has something amazing for you.
