All are commanded, therefore, to quickly repent and to simply believe in Him for everlasting life.
By God's Holy Spirit, God is always with His children. He helps us in our weakness as we walk with God and pray, bearing the fruits of God's holiness in our lives (love, joy, peace, patience, kindness, goodness, faithfulness, gentleness and self control).
The Bible is God's Word. It is Living through the Spirit of God, for by it He speaks to us. As it is God's Word, it is the infallible foundation for all we can "know" as fallible humans.
Sinners can be justified (proclaimed holy) by God & reconciled (re-united) to God, solely by the Grace of God, through the gift of Faith in Jesus Christ. It is nothing of us and we cannot boast.
