As a Brother in Christ, the male species can relate with other men and their problems. By mentoring a new Christian (someone who believes but hasnt experienced all God has to offer yet) you can be the messenger to connect someone with their salvation. We are all Brothers in Christ. We need to lead the 'lost sheep' and look for the empty vessels.
As a Sister in Christ, women can understand one another on a direct line that sometimes is impossible for your boyfriend or spouse to comprehend. God wired us all different for a reason. Being counseled by a Sister in Christ, who may have experienced some of the same issues you are going through, is priceless, and potentially life changing.
Trust in the LORD with all your heart and lean not on your own understanding; in all your ways submit to him, and he will make your paths straight.
