Neither Titus 3:5 or John 3:5 refer to baptismal regeneration, but to spiritual cleansing. See John (4:10,14: 7:37-39; 1 Corinthians 12:13).
Again, Paul is stressing the importance of love in 1 Corinthians 13 and is not teaching salvation by faith plus love/acts of charity/works.
Being merciful is descriptive of those who are born of God.
whatever!
spiritual anarchy won’t cut it
by the washing of regeneration,
baptism
faith alone is not made in prophecy in the OT or taught in the NT but faith and sacraments are
Mk 16:16 acts 8:36-38 ez 36:25-27
Heb 10:22
Let us draw near with a true heart in full assurance of faith, having our hearts sprinkled from an evil conscience, and our bodies washed with pure water.
2 Corinthians 5:17
Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.
Galatians 3:27
For as many of you as have been baptized into Christ have put on Christ.
(Born of God) faith and baptism
Jn 1:12-13 But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name:
13 Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.
1 Jn 5:4 For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, even our faith.
5 Who is he that overcometh the world, but he that believeth that Jesus is the Son of God?
6 This is he that came by water and blood, even Jesus Christ; not by water only, but by water and blood. And it is the Spirit that beareth witness, because the Spirit is truth.
7 For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one.
8 And there are three that bear witness in earth, the Spirit, and the water, and the blood: and these three agree in one.
1 pet 1:2 Elect according to the foreknowledge of God the Father, through sanctification of the Spirit, unto obedience and sprinkling of the blood of Jesus Christ: Grace unto you, and peace, be multiplied.
1 Peter 1:22
Seeing ye have purified your souls in obeying the truth through the Spirit unto unfeigned love of the brethren, see that ye love one another with a pure heart fervently: see Ez 36
