Without a basic trust there can be no fellowship. The depth of fellowship will vary according to the depth of commitment. Rom 12:10, “ Be kindly affectionate to one another with brotherly love, in honor giving preference to one another; not lagging in diligence, fervent in spirit, serving the Lord; rejoicing in hope, patient in tribulation, continuing steadfastly in prayer; distributing to the needs of the saints, given to hospitality”.
Our fellowship with one another is founded in our common commitment to Christ. Philippians 2:1-4, “Therefore if there is any consolation in Christ, if any comfort of love, if any fellowship of the Spirit, if any affection and mercy, fulfill my joy by being like-minded, having the same love, being of one accord, of one mind. Let nothing be done through selfish ambition or conceit, but in lowliness of mind let each esteem others better than himself. Let each of you look out not only for his own interests, but also for the interests of others”
