The Greek eisdechomai appears only once in the New Testament — 2 Corinthians 6:17: 'Therefore come out from them and be separate, says the Lord. Touch no unclean thing, and I will receive you (eisdexomai).' God's welcome — his eisdechomai — is conditioned on separation: the call to come out precedes the promise of reception. This is the covenantal logic of holiness.
The single occurrence of eisdechomai in 2 Corinthians 6 carries enormous weight. Paul is weaving together several OT quotations (Isaiah 52:11; Ezekiel 20:34; 2 Samuel 7:14) to make the case that the new covenant community is the new temple in which God dwells. The promise 'I will receive you' (eisdexomai) echoes the Exodus promise of divine presence following purification. Separation from what defiles is not the cause of God's love — but it is the prerequisite of his welcoming intimacy. The same Father who runs to meet the prodigal (Luke 15:20) had already watched for his return.
