'Complete' in the Bible

We are writing these things to you so that our joy [in seeing you included] may be made complete [by having you share in the joy of salvation].

Beloved, if our heart does not convict us [of guilt], we have confidence [complete assurance and boldness] before God;

There is no fear in love [dread does not exist]. But perfect (complete, full-grown) love drives out fear, because fear involves [the expectation of divine] punishment, so the one who is afraid [of God’s judgment] is not perfected in love [has not grown into a sufficient understanding of God’s love].
