'Mutual' in the Bible

Immediately Jesus called to them; and they left their father Zebedee in the boat with the hired workers, and went away to follow Him [becoming His disciples, believing and trusting in Him and following His example].

So then, let us pursue [with enthusiasm] the things which make for peace and the building up of one another [things which lead to spiritual growth].

Now may the God who gives endurance and who supplies encouragement grant that you be of the same mind with one another according to Christ Jesus,

Do not deprive each other [of marital rights], except perhaps by mutual consent for a time, so that you may devote yourselves [unhindered] to prayer, but come together again so that Satan will not tempt you [to sin] because of your lack of self-control.

so that there would be no division or discord in the body [that is, lack of adaptation of the parts to each other], but that the parts may have the same concern for one another.

And [that He] might reconcile them both [Jew and Gentile, united] in one body to God through the cross, thereby putting to death the hostility.

Therefore if there is any encouragement and comfort in Christ [as there certainly is in abundance], if there is any consolation of love, if there is any fellowship [that we share] in the Spirit, if [there is] any [great depth of] affection and compassion,

Greet one another with a kiss of love.To all of you who are in Christ, may there be peace.
