Psalm 5:8 English Standard Version (ESV) Lead me, O Lord, in your righteousness because of my enemies; make your way straight before me.

David submits to the Lord. He pleads for the Lord to show him where to go because of his enemies.

1 Peter 3:18 English Standard Version (ESV) For Christ also suffered^[died] once for sins, the righteous for the unrighteous, that he might bring us to God, being put to death in the flesh but made alive in the spirit,

Our Lord died because our sin was keeping us from coming to God. Jesus Christ removed sin as an obstacle to coming to God the Father. Sin was always the enemy, the sin of others and the sins within ourselves.

Romans 5:21 English Standard Version (ESV) so that, as sin reigned in death, grace also might reign through righteousness leading to eternal life through Jesus Christ our Lord.

Jesus Christ put an end to the reign of sin to all who have accept Him as Lord.

Then it was a matter of what the Lord will do and now it is a matter of what He has done.
