Repentance

Hebrews 6:1&2 mentions two very basic and foundational truths; repentance (from dead works) and faith (towards God).

Repentance is the first step in building a successful foundation in your new life as a believer. Faith towards God is what the Christian walk is all about.

First, God commands that man repent. There are no 'if's 'and's or 'but's about it.

And the times of this ignorance God winked at; but now commandeth all men every where to repent:
Acts 17:30

Repentance and Faith are both gifts given to us by God so that we may turn from our ways and follow His Way. Repentance and Faith are not one time deals, either. they are something that we practice throughout our Christian walk. You may have repented before God when you were saved. You will need to repent again. You may have had faith to receive Christ when you were saved. you will need faith to believe on Him again. Repentance and Faith work actively throughout your walk and sanctification.

Repentance means a "change of mind"; a change of heart or attitude. It means to have a radical change in one's own heart toward sin and the things of God. It involves a conscious moral decision to forsake sin and enter into fellowship with God.

Repentance is commanded by God (Acts 17:30)
Repentance is essential for salvation (Mark 1:15)

It is a gift from God.

He must correct his opponents with courtesy and gentleness, in the hope that God may grant that they will repent and come to know the Truth [that they will perceive and recognize and become accurately acquainted with and acknowledge it],
2 Timothy 2:25 AMP

God desires it for all men.

The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.
2 Peter 3:9
