A "successful relationship" can only be found with a person who is a Christian, who has the Lord Jesus Christ in their life and the Bible as their guide.

The Lord Jesus Christ is the same yesterday, today, forever.
His Word never changes. Those who follow Jesus, who have strong evidence in their life that they live to serve and obey Christ are the ones that can be counted on for friendships and relationships.

Women and men who want a successful relationship need to first become Christians themselves and then fill their life with other Christians. Bring Christ in to your life and the surround yourself with others who have Christ in their lives. This is success.

Any equation that does not have Jesus will fail.
