The Greek verb peirazo (πειράζω) means to test, try, or tempt — to put someone or something to the proof. It appears about 38 times in the NT. The context determines whether the testing is divine proving or satanic enticement.
The theological distinction within peirazo is crucial. God does not tempt anyone to sin (James 1:13) — but God does test faith to strengthen it (Abraham, Job, the wilderness generation). Satan tempts (peirazo) to destroy — Jesus was led by the Spirit into the wilderness to be tempted by the devil (Matthew 4:1). Jesus overcame every temptation through Scripture, becoming 'one who has been tempted in every way, just as we are — yet he did not sin' (Hebrews 4:15). This makes Him the perfect High Priest who intercedes for us in our temptations. The Lord's Prayer asks 'lead us not into temptation' — not that God leads us to sin, but that He not allow testing beyond our capacity (1 Corinthians 10:13).
