Summary:
God has given us life through the redemptive work of Christ and he is calling us to take hold of it. Part of that is by confessing what he has given us.
According to the website Bible.org, the primary Greek word for “confess” is homologeo which basically means “to say the same thing” and then “agree, admit, acknowledge.”
Scriptures:
Fight the good fight of faith. Take hold of the eternal life to which you were called, and you confessed the good confession in the sight of many witnesses.
Hebrews
10:23 (ESV) says, “Let us hold fast the confession of our hope without wavering, for he who promised is faithful.”
Romans 5:5 ESV
and hope does not put us to shame, because God's love has been poured into our hearts through the Holy Spirit who has been given to us.
1 Corinthians 13:4-8 NIV
Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. Love does not delight in evil but rejoices with the truth. It always protects, always trusts, always hopes, always perseveres. Love never fails.
